Abstract

A technique for delivery of a personalized identification number (PIN) from a centralized database of a prepaid PIN service provider along with a digital signature for verification of the transaction. As a response to a cash amount inputted by the user to a PIN vending machine, an unassigned PIN in a centralized database is assigned to the user as a unique user PIN, and delivered to the user as an imprinted receipt along with an associated digital signature for authentication.

Claims

1. A method for delivering a unique personal identification number (PIN) representative of a cash amount inputted by a user into a PIN vending machine supplied by a merchant, the method comprising

storing in a centralized database a plurality of personal identification numbers (PINs) and an escrow amount associated with the merchant,

allocating an unassigned one of the PINs as the unique PIN in response to the cash amount inputted by the user, and subtracting the inputted cash amount from the escrow amount, and

dispensing to the user from the vending machine the unique PIN along with an associated digital signature.

2. The method as recited in claim 1 wherein the dispensing includes imprinting a receipt with the unique PIN and the digital signature.

3. The method as recited in claim 1 wherein the vending machine has a unique identifier and the dispensing includes generating the digital signature with reference to the unique vending machine identifier.

4. The method as recited in claim 1 wherein the vending machine has a unique identifier and the dispensing occurs at a given date and time, and the dispensing includes generating the digital signature with reference to the unique vending machine identifier and given time and date.

5. A method for delivering a unique personal identification number (PIN) representative of a cash amount inputted by a user into a PIN vending machine supplied by a merchant wherein the vending machine has a unique identifier, the method comprising

storing in a centralized database a plurality of personal identification numbers (PINs) and an escrow amount associated with the merchant,

allocating an unassigned one of the PINs as the unique PIN in response to the cash amount inputted by the user and subtracting the inputted cash amount from the escrow amount, and

dispensing to the user from the vending machine the unique PIN along with an associated digital signature indicative of the unique identifier and information corresponding to the dispensing of the unique PIN.

6. The method as recited in claim 5 wherein the dispensing includes imprinting a receipt with the unique PIN and the digital signature.

7. The method as recited in claim 5 wherein the dispensing occurs at a given date and time, and the dispensing includes generating the digital signature with reference to the unique vending machine identifier and given time and date.

8. The method as recited in claim 7 wherein the dispensing includes imprinting a receipt with the unique PIN and the digital signature.

9. A method for delivering a unique personal identification number (PIN) representative of a cash amount inputted by a user into a PIN vending machine supplied by a merchant, the method comprising the steps of

storing in a centralized database a plurality of personal identification numbers (PINs) and an escrow amount associated with the merchant,

allocating an unassigned one of the PINs as the unique PIN in response to the cash amount inputted by the user, and subtracting the inputted cash amount from the escrow amount, and

dispensing to the user from the vending machine the unique PIN along with an associated digital signature.

10. The method as recited in claim 9 wherein the step of dispensing includes the step of imprinting a receipt with the unique PIN and the digital signature.

11. The method as recited in claim 9 wherein the vending machine has a unique identifier and the step of dispensing includes the step of generating the digital signature with reference to the unique vending machine identifier.

12. The method as recited in claim 9 wherein the vending machine has a unique identifier and the step of dispensing occurs at a given date and time, and the step of dispensing includes the step of generating the digital signature with reference to the unique vending machine identifier and given time and date.

17. The method as recited in claim 16 wherein the vending machine has a unique identifier and the step of dispensing includes the step of generating the digital signature with reference to the unique vending machine identifier and the time and date of the response.

18. The method as recited in claim 17 wherein the step of dispensing includes the step of imprinting a receipt with the unique user PIN and the digital signature.

20. The method as recited in claim 19 wherein the vending machine has a unique identifier and the step of dispensing includes the step of generating the digital signature with reference to the unique vending machine identifier and the time and date of the transaction response.

13. A method for transmitting a unique personal identification number (PIN) representative of a cash amount inputted by a user into a PIN vending machine supplied by a merchant, the method comprising

storing in a centralized database a plurality of personal identification numbers (PINs) and an escrow amount associated with the merchant,

allocating an unassigned one of the PINs as the unique PIN in response to the cash amount inputted by the user, and subtracting the inputted cash amount from the escrow amount, and

sending to the user the unique PIN along with information for providing an associated digital signature.

14. A method for receiving a unique personal identification number (PIN) representative of a cash amount inputted by a user into a PIN vending machine supplied by a merchant, the method comprising

sending from the vending machine to a centralized database containing a plurality of personal identification numbers (PINs) a request for an allocation of the unique PIN in response to the cash amount inputted by the user,

receiving an allocated one of the PINs as the unique PIN, and

dispensing to the user from the vending machine the unique PIN along with an associated digital signature.

15. A method for receiving a unique personal identification number (PIN) representative of a cash amount inputted by a user into a PIN vending machine supplied by a merchant, the method comprising
