Description

FIELD OF THE INVENTION

The present invention generally relates to a system and method for allowing customers and businesses to purchase pre-paid goods and services. The present invention more specifically relates to a system and method for distributing personal identification numbers (PINs) for access to pre-paid goods and services to users over a computer network.

BACKGROUND OF THE INVENTION

There currently exist "pre-paid" telephone cards that allow a customer to purchase a desired amount of long-distance telephone time from a particular telephone service provider. These pre-paid telephone cards are often sold by dealers such as convenience stores or wireless phone stores. Pre-paid telephone cards are also often sold in airports. Vending machines for selling pre-paid telephone cards also have been developed. Each of these pre-paid telephone cards has a specific monetary denomination. For example, a customer could purchase a $10 card, a $20 card, or a $100 card. These pre-paid telephone cards are sold by particular telephone service providers such as AT&T, MCI, Sprint, etc. A customer could, for example, buy a $20 MCI card, which would entitle him or her to $20 worth of long-distance calling service provided by MCI. These cards are referred to as "pre-paid" because the customer purchases the long-distance time before he or she actually places the call. This is in contrast to the more typical post-pay service that most telephone customers use with the telephone in their residence or office. With post-pay service, customers are sent a bill on a periodic basis. The customer pays for calls that have already been made, rather than calls that will be made in the future.

Frequently, the pre-paid telephone cards that are sold by dealers or vending machines are of the "scratch-off" type. After the customer purchases a card, he or she can scratch off a layer of material which reveals a personal identification number (PIN). The layer of scratch-off material hides the PIN from customers browsing in the store who have not purchased the card. After a customer purchases a card and scratches off the layer of material, the customer can then use the card to place a long-distance call. When the customer wishes to place a long-distance call, he or she dials a special number provided by the telephone service provider. The customer then enters the PIN written on the card. The long distance provider automatically debits the charge of the call from an account associated with the PIN.

As an example, a customer could purchase a $10 MCI card. After the customer rubs off the layer of material, a PIN number 129384348764 is revealed. When the customer wishes to place a long-distance call, the customer dials an MCI access number. The customer then enters PIN 129384348764. The long-distance carrier, MCI, identifies the PIN and recognizes that there is $10 worth of credit in this account. If the customer places a call which lasts 5 minutes and costs 4$, MCI will debit the account so that $6 remains. The next time the customer places a call using that PIN number, the system will find that $6 remains in the account associated with that PIN.

One problem with these pre-paid phone cards is that the cards present a major inventory headache for dealers. There is a lot of work and expense associated with maintaining a filled inventory of cards. First, the dealer or vending machine operator has to predict which cards will be in demand and determine how many cards of each denomination to order for each of various providers. The dealer then has to pay for the desired inventory of cards up front, which requires a significant cash outlay. The dealer then has to keep track of how many cards are left in stock for each service provider and of each different monetary denomination, and determine when to order a new batch of cards. All of these costs associated with filled inventory can be time consuming and expensive for dealers.

Another problem is that these pre-paid telephone cards are especially vulnerable to theft, loss, and other inventory "shrinkage." Because the cards are small, it is easy for a shoplifter to pocket a card unnoticed. Since these cards have a high value to them and are so easy to pocket, dealers which sell these cards are extremely vulnerable to inventory shrinkage.

Vending card machines have been proposed which store personal identification numbers (PINs) in a memory in the machine. A customer can then purchase a pre-paid telephone PIN by inserting cash into the machine. The machine can replenish its stock of PINs when the memory runs out of PINs or on a periodic basis by accessing a remote store of PINs via a modem.

The problem with these vending machines is that there are still significant costs associated with inventorying the PINs. The PINs are retained in a memory in the machine which has a similar effect to storing cards. Once a PIN has been stored in the memory of a particular machine, that PIN becomes unavailable to be used by any other dealer, even if the PIN is never purchased. Additionally, if the machine were to break, or the memory were to be erased, there is a problem determining who is responsible for paying for the PINs that were contained in the memory. Additionally, decisions must still be made how many PINs to store in memory, what monetary denominations to store in memory, and for which providers to store PINs in memory. Therefore, there are still significant inventory costs associated with storing the PINs in the vending machine. Additionally, these proposed vending machines do not provide consumers the ability to obtain a PIN from the convenience of their homes or offices.

Another system which has been proposed is a web site which is accessed over the Internet. A customer can go to this web site and purchase pre-paid telephone service. A PIN is then e-mailed to the customer's e-mail address. The problem with this service is that a customer must be able to access his or her e-mail account in order to obtain the PIN. Additionally, e-mail is often unsecure. If a computer hacker is "listening in" on an individual's email, then the hacker can steal the PIN and use it for his own purposes. Additionally, if a customer is purchasing a PIN in a convenience store or an airport, the customer will probably not have access to his or her e-mail account. The customer may have to wait to return to his or her home or office to access the PIN. Additionally, e-mail can sometimes be slow and it may take hours or days to retrieve the message from the customers Internet Service Provider (ISP).

What is needed is a secure system that provides PINs for pre-paid goods and services conveniently to customers. What is also needed is a system that relieves dealers such as convenience stores and vending machine operators from the costs associated with maintaining a filled inventory of pre-paid cards and PINs. What is also needed is a system that allows consumers to select from a wide-range of providers and monetary denominations without requiring the dealer to maintain a large filled inventory of cards or predict which type of cards or PINs to order. What is also needed is a secure system for selling pre-paid goods and services which is less vulnerable to theft and other inventory shrinkage. What is also needed is a system that can peform real-time distribution and accounting of personal identification numbers.

SUMMARY OF THE INVENTION

The present invention allows a customer to purchase pre-paid amounts of any good or service, such as telephone service, gasoline, electricity, dry-cleaning, bus service, subway service, magazines, newspapers, or bundled goods and services. After the customer purchases a pre-paid amount of a good or service, the customer receives a personal identification number (PIN) which is downloaded in real-time over a network such as the Internet. The PIN is provided over the network "on-demand," meaning that the PIN is downloaded over the network immediately or very soon after receiving a request and payment from the customer. The PIN is downloaded over a network in response to the customer's request, not delivered to the customer hours or days after the request. The PIN is not stored locally at the client terminal used by the customer, but is downloaded over the Internet, thus eliminating any inventory tasks or costs associated with maintaining a filled inventory for the dealer. After the customer receives the PIN, the customer can then use this PIN at any convenient time to access the desired good or service.

The present invention thus provides "virtual inventory" of pre-paid cards because it removes all the burdens of inventorying pre-paid cards from the dealer. Additionally, it provides "virtual distribution" of telephone cards, because the service providers no longer have to manufacture pre-paid cards and distribute them to the dealers. Because the PINs are delivered on-demand, the present invention provides real-time distribution and accounting. Additionally, the present invention eliminates the inventory shrinkage problem created by the loss and theft of pre-paid cards.

The present invention comprises a system and method for providing a personal identification number (PIN) to a client terminal over a computer network. The invention eliminates all costs associated with filled inventory for dealers selling PINs. In accordance with one aspect of the present invention, a server receives a request for a PIN over a network, the request originating from a user at a client terminal. The request is associated with a requested monetary unit and a requested provider. The server retrieves from a database a PIN associated with the requested monetary unit and requested provider. The server transmits the retrieved PIN to the client terminal over the network, wherein the PIN is transmitted to the client terminal on-demand in response to the customer's request. No inventory of PINs is stored at the client terminal. All transmissions between the client terminal and the server are by secure transmission to prevent an eavesdropper from stealing the PIN(s).

The PIN can be used for accessing pre-paid telephone service. Alternatively, the PIN can be used for accessing other pre-paid goods and services such as gasoline, magazines, subway service, etc.

The server can transmit to the client terminal a plurality of products or services available. The server then receives from a user at the client terminal a selection of one of the available products or services. The server transmits to the client terminal a plurality of provider names for the requested product or service. The server receives from a customer at the client terminal a selection of one of the available provider names. The server transmits to the client terminal a plurality of monetary denominations available for the requested provider. The server receives from the client terminal a selection of one of the available monetary denominations. The server transits to the client terminal a plurality of regions available for the requested provider. The server receives from the client terminal a selection of the one of the available regions. The server can receive a request from the client terminal to view rate information. The server then transmits rate information to the client terminal.

The user is then prompted at the client terminal to enter payment for the requested PIN. The user can enter payment a) inserting cash into a receptacle at the client terminal, or b) entering credit card or debit card or smart card information or swiping a card through a receptacle, or c) paying cash to an operator associated with the client terminal. If the user pays a dealer, the dealer remits a portion of the payment to an account associated with the server by a) transferring funds from a dealer's account into the account associated with the server by an electronic funds transfer, or b)charging a portion of the payment to a dealer's credit account, or c) charging a portion of the payment to a dealer's credit card.

After the user pays for one or more PINs, the client terminal prints a receipt for the customer, the receipt including the requested PIN number and instructions for using the PIN.

The present invention also includes a purchase ordering method whereby a dealer can buy PINs in bulk and receive a wholesale discount. The dealer can place multiple individual purchase orders at once, each individual purchase order associated with a requested provider, a requested monetary denomination, and a requested number of PINs.

DETAILED DESCRIPTION OF THE INVENTION

The present invention allows a customer to purchase pre-paid amounts of any good or service, such as telephone service, gasoline, electricity, dry-cleaning, bus service, subway service, magazines, newspapers, or bundled goods and services. After the customer purchases a pre-paid amount of a good or service, the customer receives a personal identification number (PIN) which is downloaded in real-time over a network such as the Internet. The PIN is provided over the network "on-demand," meaning that the PIN is downloaded over the network immediately or very soon after receiving a request and payment from the customer. The PIN is downloaded over a network in response to the customer's request, not delivered to the customer hours or days after the request. The PIN is not stored locally at the client terminal used by the customer, but is downloaded over the Internet, thus eliminating any inventory tasks or costs associated with maintaining a filled inventory for the dealer. After the customer receives the PIN, the customer can then use this PIN at any convenient time to access the desired good or service.

The present invention thus provides "virtual inventory" of pre-paid cards because it removes all the burdens of inventorying pre-paid cards from the dealer. Additionally, it provides "virtual distribution" of telephone cards, because the service providers no longer have to manufacture pre-paid cards and distribute them to the dealers. Additionally, the present invention eliminates the inventory shrinkage problem created by the loss and theft of pre-paid cards.

FIG. 1 depicts a block diagram of the system of the present invention. Easywireless.com server 102 is coupled to network 104. Server 102 can be any large computer or network device. The name "Easywireless.com" used herein in conjunction with server 102 is used by way of example only, and is not intended to in any way limit the range of servers that can be used with the present invention. For purposes of example only, "Easywireless.com" server 102 refers to a server associated with the company Easywireless, Inc.

Network 104 can be any network connecting computers such as the Internet. Client terminals 106, 108, and 110 are running browser programs 128, 130 and 132, respectively. Browsers 128, 130, and 132 are any program that allows client terminals 106, 108, and 110 to access Easywireless.com server 102 over network 104.

Easywireless.com server 102 contains RAM 114, ROM 116, CPU 118, and data storage device 120. CPU 188 runs the software which is operating the method of the present invention depicted in FIG. 2. Data storage device 120 contains a personal identification number (PIN) database 112. PIN database 112 stores PINs which are available for purchase by customers. The PIN provides access to a pre-paid amount of a good or a service. PIN database 112 is described in more detail with respect to FIG. 3.

Data storage device 120 also includes client terminal records 122. Client terminal records store information concerning where client terminals are located. Client terminal records 122 can store any information specific to specific client terminals, such as previous purchase history, payment and account information, and terminal preferences.

Data storage device also includes customer records 123. Customer records 123 provide information unique to individual customers. For example, as will be discussed later with respect to FIG. 2C, customers can access Easywireless.com server 102 through a home personal computer. Customers can identify themselves and provide identifying information. Easywireless.com 102 can use this information to provide better service to the customer, to target advertising to the customer, or to store payment or credit accounts. When a customer accesses Easywireless.com server 102 from a client terminal in a retail store, in most instances the customer will prefer to remain anonymous. In this case, Easywireless.com server 102 will not store any customer information in customer records 123.

Data storage device 120 also contains provider records 124. These records contain information pertinent to providers who are providing PINs for PIN database 112. For example, these records can contain addresses, billing information, and telephone numbers. Data storage device 120 also contains advertising records 126. Advertising records 126 contain information about advertising banners and links that can be provided to client terminals 106, 108 and 110 as an additional source of revenue.

Because the PINs are valuable and could be subject to theft and copying by electronic piracy, communications over network 104 between Easywireless.com server 102 and client terminals 106, 108 and 110 is protected by the use of encrypted communications and well-known security techniques. Client terminals 106, 108, and 110 can provide security certificates to Easywireless.com server 102 to authenticate their transmissions.

FIGS. 2A-2C depict three alternative physical embodiments of client terminals 106, 108 and 110. FIG. 2A depicts a physical embodiment which is used in a typical checkout counter of a store, such as a convenience store. Client terminal 200 of this embodiment includes a touch-screen 204. Various options appear on touch-screen 204, which a customer may activate by touching an appropriate location on touch-screen 204. A customer makes payment by paying cash to a store clerk operating cash register 202. Alternatively, a customer can pay with a credit card by swiping a credit card through credit card slot 208. Buttons 206 can be used by the customer in addition to touch-screen 204 to make additional selections, such as choosing a particular type of credit card.

FIG. 2B depicts an alternative physical embodiment for the client terminal, automated kiosk 210. Automated kiosk 210 includes a touch-screen 212. Credit card receptor 214 allows a consumer to submit payment by inserting a credit card. Alternatively, the customer can insert bills into bill receptor 218, or coins into coin receptor 220. The customer can optionally make selections by entering data on keypad 216 in addition to making selections with touch-screen 212.

FIG. 2C depicts another alternative physical embodiment for a client terminal. Personal computer 222 can be used in the convenience of a customer's home or office to access the Easywireless.com web server, by entering an appropriate URL in the customer's browser (for example, http://www.Easywireless.com). The customer can then purchase PIN(s) from Easywireless.com from the customer's personal computer 222.

FIG. 3 depicts a simplified example of records within PIN database 112. Another, more detailed example of records within PIN database 112 is described later with respect to FIGS. 19A and 19B. PIN database 112 stores PINs which are available for purchase by customers. PIN database 112 contains records 312. Good/Service field 301 specifies the name of a good or service which is available for pre-paid purchase. For example, records 312a-312p shown in FIG. 3 contain PINs which provide access to pre-paid cellular service. Records 312q-r shown in FIG. 3 contain PINs which provide access to pre-paid gasoline. Other goods and services can be also be included in PIN database 112 such as electricity, cable service, satellite TV, etc.

Provider field 302 contains the name of the particular good or service provider associated with the record. For example, FIG. 3 shows records for AT&T, AIRTOUCH, SPRINT, and MOBIL. Value field 304 specifies the dollar value associated with each record. For example, record 312h provides a customer with $50 of pre-paid cellular service from AIRTOUCH. PIN field 306 specifies the PIN which is provided to the customer and allows access to the good or service. Rate field 308 specifies a rate associated for each record. For example, for cellular telephone service rate field 308 specifies the calling rate associated with the record. In the example PIN database 112 shown in FIG. 3, rate field 308 is not used for gasoline records 312q and 312r, since the gasoline rate is determined at the pump.

Expiration field 310 contains an expiration date beyond which the PIN for that record will no longer be valid. Other fields may also be added. Some fields may be particular to a specific good or service. For example, if gasoline is being sold then there may be a field for "Octane" which specifies the octane level of gasoline being purchased.

FIG. 4A depicts a flowchart illustrating a method of operating Easywireless.com server 102. Initially, in step 400, the Easywireless.com server receives a request from a customer to begin. For example, a customer entering a retail store approaches client terminal 200 shown in FIG. 2A. A "BEGIN" Window displayed on touch-screen 204 reads "Touch here to begin." The customer approaches the touch-screen 204 and touches the BEGIN Window. This sends a request to begin to Easywireless.com server 102.

In step 402, in response to receiving a request to begin, Easywireless.com server 102 transmits to the client terminal a list of products and services offered. For example, Easywireless.com server 102 could transmit: 1) cellular telephone service, 2) long-distance telephone service, 3) electricity, 4) gasoline, and so on. All of these goods and services would be available to the customer to purchase on a pre-paid basis. The list of products and services transmitted to the client terminal appears, for example, on touch-screen 204 shown in FIG. 2A. The customer then touches a desired good or service on touch-screen 204. This sends a request for the chosen good or service back to Easywireless.com server 102. For example, the customer selects "cellular telephone service."

In step 404, Easywireless.com server 102 receives the request from the client terminal for the chosen good or service. In this example, Easywireless.com server 102 receives a request for cellular telephone service. In step 406, the Easywireless.com server 102 transmits to the client terminal a list of providers for the requested good or service. For example, if the customer has requested cellular telephone service, Easywireless.com server 102 transmits a list of: AT&T, AIRTOUCH, and SPRINT. The customer then selects one of these offered providers by touching an option on touch-screen 204. This would send a request back to Easywireless.com server 102 for a particular requested provider. For example, the customer could select "AIRTOUCH."

In step 408, Easywireless.com server 102 receives the customer's request for the particular provider requested.

In step 409, Easywireless.com server 102 transmits to the client terminal a list of regions for the requested good or service. For example, if the customer requested "AIRTOUCH" in step 408, then Easywireless.com server 102 would transmit a list of regions such as "AIRTOUCH NORTHEASTERN U.S.," or "AIRTOUCH NEW YORK CITY METROPOLITAN REGION," OR "AIRTOUCH PACIFIC REGION," etc. In step 410, Easywireless.com server 102 receives the customer's request for a particular region.

In step 411, Easywireless.com server transmits a list of pre-paid monetary denominations offered. For example, if a request for "AIRTOUCH" is received, Easywireless.com might offer pre-paid cellular service for AIRTOUCH in the following monetary denominations: $10, $20, $50, and $100. Thus a customer could choose to buy a $50 "virtual" phone card which would provide him or her with $50 of pre-paid cellular service.

The Easywireless.com server 102 can determine what monetary denominations are available by one of the following methods. As a first method, Easywireless.com server 102 checks provider records 124, and looks up the record corresponding to the chosen provider (for example, AIRTOUCH). Easywireless.com 102 then checks a field of the provider record to determine what monetary values are offered. As a second method, Easywireless.com server 102 checks PIN database 112, and determines what types of monetary denominations are available. For example, Easywireless.com server 102 can determine that it is presently out of stock of $50 AIRTOUCH PINs, but Easywireless.com server 102 has available $10 PINs, $20 PINs, and $100 PINs. As an example, the customer could choose to purchase a $50 PIN from AIRTOUCH. The customer would receive a PIN which would allow him or her to purchase $50 of cellular telephone service.

As an alternative to transmitting a list of offered monetary denominations, in step 410, the customer could alternatively be allowed to simply type in at a keypad a desired amount of service that he or she desires. For example, a message would appear on touch-screen 204 stating "TYPE IN AN AMOUNT OF PRE-PAID SERVICE YOU WISH TO PURCHASE." The customer could then type in, for example, $50. Easywireless.com server 102 could then check PIN database 112 to see if it had any $50 PIN denominations available. If there was no $50 PINs available, Easywireless.com server 102 could, for example, transmit a message stating "THERE ARE NO $50 PINS AVAILABLE. WOULD YOU LIKE TO PURCHASE A $40 PIN OR A $75 PIN?" Alternatively, Easywireless.com server 102 could transmit a message stating "THERE ARE NO $50 PINS AVAILABLE FOR AIRTOUCH. HOWEVER, SPRINT AND MCI OFFER $50 PINS FOR CELLULAR TELEPHONE SERVICE. WOULD YOU LIKE TO PURCHASE FROM ONE OF THESE PROVIDERS?"

The customer can also be given an option to "View Rates." If the customer chooses this option, then a request to view rates is sent to the Easywireless.com server 102. In step 412, the request is received by Easywireless.com server 102. In step 414, Easywireless.com server 102 transmits rate information to the client terminal. For example, the rate information could specify that a $100 "virtual" pre-paid phone card purchased from AIRTOUCH has a cellular calling rate of $0.35 per minute, and the PIN expires in 6 months. A $50 virtual pre-paid phone card purchased from AIRTOUCH has a cellular calling rate of $0.40 per minute, and the PIN expires in 8 months. Providers may choose to offer lower rates for larger pre-paid purchases as a high volume discount. Further information can also be requested and provided to the customer depending on the particular product or service purchased. For example, if the customer is purchasing gasoline, the customer could request current price per gallons at various gas station locations for various octane levels.

In step 416, Easywireless.com server 102 receives from the client terminal a request for one of the available monetary denominations. For example, the customer could select an option to purchase a $50 PIN from AIRTOUCH by touching the appropriate option on touch-screen 204.

In step 418, Easywireless.com prompts the customer at the client terminal to make payment for the requested PIN. Payment can be made by the customer in a number of ways. In the embodiment shown in FIG. 2A, the customer can pay the dealer by cash, credit card, debit card, smart card or any similar method (the customer pays a cashier behind cash register 202). Once the customer pays the dealer, then the dealer must transfer a portion of the payment to Easywireless.com Payment can be apportioned and transferred between the dealer and Easywireless.com by a number of methods. Some example methods:

First method "ACH WALLET": The dealer has a special account set up with Easywireless.com. The dealer stores money in the account before the PIN is purchased. Immediately before a customer purchases one or more PINs, the dealer pays a portion of the payment to Easywireless.com by transferring money from the dealer's account to Easywireless.com by ACH (automated clearing house) electronic funds transfer. This method of payment is referred to as "ACH wallet."

Second method "CREDIT ACCOUNT": The dealer has a credit account with Easywireless.com. The dealer is allowed a predetermined amount of credit based on the creditworthiness of the dealer. When a customer pays for one or more PINs, a portion of the payment is charged to the dealer's credit account. The dealer is then billed later for the amount charged.

Third method: The dealer simply provides credit card information to Easywireless.com. When customer purchases one or more PINs, a portion of the payment is charged to the dealer's credit card.

Fourth method: The customer's credit card information (or debit card, or smart card) is sent directly to Easywireless.com. Easywireless.com then charges the customer's credit card and sends a portion of the payment back to the dealer.

As will be understood by one skilled in the art, the above methods are by example only and there are a multitude of ways that payment can be arranged between the dealer and Easywireless.com. All of these methods do have one thing in common, however. The PIN is sent by Easywireless.com right after a payment is made (either by cash or credit). This makes the delivery of the PIN "on demand" and eliminates costs associated with filled inventory. Because the PIN is sent right after payment is made, the dealer has no costs associated with filled inventory. For example, the dealer does not have to contact Easywireless.com at the beginning of each month and order $10,000 worth of cards. The dealer does not have to predict which cards will be popular, and how many cards to order of each type. Payment for the PIN is charged at the time of each transaction, and thus the dealer has no filled inventory costs.

In the automated kiosk embodiment shown in FIG. 2B, the customer can enter payment by swiping a credit card through credit card receptor 214, or inserting cash into bill receptacle 218 or coin receptacle 220. Using the personal computer of FIG. 2C, the customer can enter payment by typing in his or her credit card information.

After payment has been received and verified in step 418, then in step 420 Easywireless.com server retrieves a PIN from the database having the appropriate characteristics selected by the customer. For example, if the customer chose to purchase a $50 virtual pre-paid phone card for pre-paid cellular telephone service from AIRTOUCH, then Easywireless.com server 102 could retrieve record 312f shown in FIG. 3. In step 422, Easywireless.com web server transmits PIN 0948574995 (this PIN is shown in PIN field 306 of exemplary record 312f in FIG. 3) to the customer at the client terminal. Once a PIN has been retrieved from PIN database 112 and transmitted to the customer, the PIN record is marked as sold and unavailable from PIN database 112 so that it will not be sent to another customer. Alternatively, the PIN record can be marked as used, so that it will not be retrieved for another customer.

Easywireless.com web server 102 also transmits any instructions necessary to use the PIN. For example, Easywireless.com can transmit a telephone access number which the customer needs to dial before placing a cellular telephone call and entering the PIN. The telephone access number and other instructions will be unique for each provider. These instructions can either be stored in each individual record 312 in PIN database 112, or the instructions can be stored in provider records 124.

The customer could also request to receive multiple PINs. For example, the customer could purchase 3 $50 PINs for AIRTOUCH cellular telephone service. After the customer enters $150 in payment, Easywireless.com server 102 transmits 3 $50 PINs to the customer at the client terminal.

At step 424, the client terminal prints out a receipt for the customer. The receipt includes the requested PIN(s) purchased by the customer, and any instructions for using the PIN such as a telephone access number. The receipt can also contain advertisements. Advertisers pay Easywireless.com for the opportunity to have their ads displayed on receipts. The receipt is a printed piece of paper. Alternatively, the receipt could be in the form of a plastic card. Easywireless.com server 102 then returns back to the first step 400, waiting for the next customer to request to "BEGIN".

FIG. 5 depicts a flowchart illustrating a method of operation of client terminals 106, 108, 110 (shown in FIG. 1), 200, 210, and 222 (shown in FIG. 2). FIGS. 6-10 show exemplary displays to be shown on the screen of the client terminal. The method of operation will now be described with reference to the flowchart of FIG. 5 and the screens shown in FIGS. 6-10.

In step 500, a window appears which states "TOUCH HERE TO BEGIN." The customer can begin by touching the touch-screen 204 or 212 in the appropriate location. If the customer has accessed the Easywireless.com web server 102 by using personal computer 222, the customer can begin by entering an appropriate URL into the browser (such as http://www.easywireless.com). This would bring the customer to the Easywireless.com web page running on Easywireless.com server 102. The customer could click on a link labeled "BEGIN" to begin the purchase process.

In step 501, the client terminal displays list of offered goods and services, such as cellular telephone service, gasoline, electricity, dry-cleaning, etc. The customer can then choose one of these goods or services to purchase. Assume, for this example, that the customer has selects "cellular telephone service". In step 502, the customer is provided with a list of providers for the chosen good or service and asked to choose a provider. FIG. 6 shows an exemplary screen corresponding to step 502 (assuming that the customer has selected "cellular telephone service"). Touch-screen 600 displays browser window 604. Four service provider options are shown: AIRTOUCH option 608, PRIMUS option 606, SPRINT option 610 and AT&T option 612. For the purposes of this example, assume that a customer touches AIRTOUCH option 608.

In step 504 the display screen displays virtual cards of various monetary options which are offered for the chosen good or service provider (which in this example is AIRTOUCH). FIG. 7 shows an exemplary display screen corresponding to step 504. Four possible monetary denominations may be selected. The customer can choose the $15 option 708, $30 option 706, $50 option 710, or $100 option 712.

In step 506, the display screen displays rate information, if desired by the customer. The customer is given the option of viewing rates by touching the VIEW RATES option 714 shown in FIG. 7. If the customer decides to touch VIEW RATES option 714, then in step 506, the screen displays calling rates, card expiration dates, or any other information applicable to the chosen good or service, or specific to the particular good or service provider chosen. For example, if the customer who has chosen to purchase AIRTOUCH cellular service, touches the VIEW RATES option 714, then FIG. 8 shows an exemplary screen. Information window 800 provides a number of information fields. Card value field 802 displays the various virtual card monetary values offered. Local rates field 804 displays the calling rate per minute for each card value. Expiration field 806 displays the expiration date beyond which the PIN is no longer usable. As shown in FIG. 8, AIRTOUCH offers a discount for higher value card purchases. In other words, the calling rate goes down for higher card value purchases. By touching the continue field 808, the customer can return to the screen shown in FIG. 7.

In FIG. 7, the customer selects a particular monetary denomination offered by touching the screen in an appropriate location. In this example, assume that the customer has chosen the $100 virtual card option 712. This brings up the display shown in FIG. 9. In step 508, the customer is given the choice of how many cards he or she wishes to purchase. The quantity of cards window 908 in FIG. 9 displays the number of virtual cards to be purchased. The customer can touch arrow 910 to increment the number of virtual cards to be purchased. The number of cards to be purchased is shown in box 912. The customer can touch arrow 914 to decrement the number of virtual cards to be purchased. Field 900 and virtual card 906 display the monetary value of the virtual card that was chosen by the customer. Local rates field 902 displays the calling rate for the chosen virtual card. Expiration field 904 displays when the virtual card will expire.

If the customer changes his or her mind, and wishes to purchase a card with a different value, the customer can return to the screen shown in FIG. 7 by touching the CHANGE CARD field 918. Otherwise, the customer can proceed by touching the CONTINUE field 916. This brings up the display shown in FIG. 10A, corresponding to step 510. Field 1000 displays the total purchase price. Since the customer has requested to purchase two pre-paid virtual $100 cards from AIRTOUCH, the total purchase price is $200. Field 1002 instructs the customer to insert payment. This message could alternatively tell the customer to enter credit card information, swipe a credit card, a debit card, a smart card, or pay cash to a cashier depending on the particular client terminal being used and/or a chosen method of payment.

In step 512, payment is received from the customer. After payment has been received and verified, Easywireless.com server 102 retrieves the requested PIN(s) from PIN database 112 and transmits the requested PIN(s) to the client terminal in step 514. The PIN(s) can be displayed on the screen as shown in FIG. 10b, field 1004. Message 1006 informs the customer to take a receipt. A receipt is printed out in step 516. The receipt will contain the requested PIN(s) and any instructions necessary for using the PIN such as an access number to call. If privacy is a concern, it might be preferable not to display the PINs on the screen, but instead to only print the PINs on the receipt.

FIGS. 11 and 12 depict a flowchart illustrating a method of using the PIN once the customer has received the PIN from Easywireless.com server 102. FIG. 11 shows an exemplary method which assumes that the customer has purchased pre-paid telephone service. As an example, assume that a customer has purchased $50 of pre-paid telephone service. A receipt was printed out for the customer providing a PIN and a telephone access number. In step 1100, the customer dials the access number which was provided on the receipt. Typically, the access number is specific to the chosen service provider. For example, if the customer has previously purchased $50 of pre-paid telephone service from AIRTOUCH, the customer will be given an AIRTOUCH access number. When the customer dials the access number, the customer's call will be routed to a switch operated by AIRTOUCH. The access number is preferably a toll-free 1-800 number or a local number. In step 1102, the customer is prompted to dial the destination number that he or she wishes to call. In step 1104, the customer is prompted to enter a PIN which was printed out on the receipt. The customer then dials in his or her PIN. An AIRTOUCH server then checks a PIN account for the entered PIN. In step 1106, the AIRTOUCH server checks to see how much money is remaining in the account. If there is enough money left in the pre-paid account to place the desired call, then the call to the destination number is placed in step 1108. While the call is continuing, the PIN account is debited in accordance with the calling charges. In step 1110, if the account value reaches zero, the customer is informed that a new PIN must be purchased or additional payment must be made. As an option, the customer can be allowed to dial in a credit card number to continue with the call.

FIG. 12 depicts a flowchart illustrating a similar method to FIG. 11. However, FIG. 12 depicts an example where the customer has purchased pre-paid gasoline. For this example, assume that a customer has previously purchased $50 of pre-paid MOBIL gasoline. A receipt was printed out for the customer providing a PIN. In step 1200, the customer arrives at a local MOBIL gas station. The customer uses a keypad and display screen at a self-service pump. The customer pushes a button indicating that he or she wishes to pay with a pre-paid PIN account. In step 102, the customer is prompted to enter a PIN. The customer enters the PIN for which he or she pre-paid. The PIN is sent to a server operated by MOBIL. The server checks a PIN account for that PIN to determine how much money is remaining in the account. If there is money left in the pre-paid account, then the customer is told to begin pumping. The pre-paid PIN account is then debited in accordance with charges for the gasoline pumped. If the account reaches zero, the customer is informed that additional payment must be made.

Easywireless.com server 102 essentially serves as a PIN warehouse. The operators of Easywireless.com server 102 can
