Method, system, and computer program product for implementing pin-based data transfer activities
A system for implementing personal identification number (PIN)-based data transfer activities includes a host system and a PIN generator application and encryption engine executing on the host system. The PIN generator application and the encryption engine generate an instance of a PIN by the PIN generator application in response to a request by a holder of an instrument to create the PIN. Generation of the instance of the PIN includes receiving an instrument identifier and a data value from the holder of the instrument, retrieving a transfer system key and a seed value associated with the instrument from an account record associated with the instrument identifier, and encrypting the instrument identifier, the data value, the transfer system key, and the seed value to form the instance of the PIN. The instance of the PIN is provided to the holder of the instrument. The data value is encoded on the instrument.

4. The system of claim 1 , wherein generating the instance of a PIN further comprises:
receiving purse information from the holder of the instrument, the purse information including an identification of a location on the instrument to which the data value will be transferred; and encrypting the purse information along with the instrument identifier, the data value, the transfer system key, and the seed value to form the instance of the PIN.
5. The system of claim 1 , wherein the PIN generator application further performs:
re-synchronizing the seed value used by the transfer system and the PIN generator application when the seed value used in the encrypting differs from a seed value retrieved by the transfer system.
6. The system of claim 1 , wherein generating the instance of a PIN further includes obtaining authorization to debit or charge an account for the amount of a value, used as the data value to be transferred to the instrument, prior to generating the PIN.
7. The system of claim 1 , wherein the data value encoded on the instrument is used for receiving goods or services from a vending station or providing access to a secure physical location, the vending station including at least one of:
a beverage vending machine;
a food vending machine;
a document reproduction machine;
a clothes washing machine;
a clothes-drying machine;
a vehicle parking meter;
a jukebox;
a gaming device;
a tanning station;
a point of sale (POS); and,
a security access system.
8. The system of claim 7 , wherein the account record stores vending system identifiers for vending stations associated with the transfer system that services the instrument.
9. A method for implementing personal identification number (PIN)-based data transfer activities, comprising:
generating an instance of a PIN by a PIN generator in response to a request by a holder of an instrument to create the PIN, the PIN used in transferring a data value to the instrument, the data value including at least one of a value of products or services, and a function to be performed via the instrument, the generating comprising:
receiving an instrument identifier and the data value from the holder of the instrument;
retrieving a transfer system key and a seed value associated with the instrument from an account record associated with the instrument identifier; and
encrypting the instrument identifier, the data value, the transfer system key, and the seed value to form the instance of the PIN; and
providing the instance of the PIN to the holder of the instrument;
wherein the data value is encoded on the instrument in response to: providing the instrument to a transfer system associated with the transfer system key; providing the PIN to the transfer system by the holder of the instrument; decrypting the PIN; and validating the instrument identifier, the transfer system key, and the seed value.
10. The method of claim 9 , wherein the transfer system is communicatively decoupled from the PIN generator.
11. The method of claim 9 , further comprising:
generating a new seed value for the instrument upon completing generation of the instance of the PIN; and
updating the new seed value in the account record for use in generating another PIN in response to another request to generate a PIN.
12. The method of claim 9 , wherein generating the instance of a PIN further comprises:
receiving purse information from the holder of the instrument, the purse information including an identification of a location on the instrument to which the data value will be transferred;
and encrypting the purse information along with the instrument identifier, the data value, the transfer system key, and the seed value to form the instance of the PIN.
13. The method of claim 9 , further comprising re-synchronizing the seed value used by the transfer system and the PIN generator when the seed value used in the encrypting differs from a seed value retrieved by the transfer system.
14. The method of claim 9 , wherein generating the instance of a PIN further includes obtaining authorization to debit or charge an account for the amount of a value, used as the data value to be transferred to the instrument, prior to generating the PIN.
15. A computer program product for implementing personal identification number (PIN)-based data transfer activities, the computer program product including instructions for causing a computer to implement a method, comprising:
generating an instance of a PIN by a PIN generator in response to a request by a holder of an instrument to create the PIN, the PIN used in transferring a data value to the instrument, the data value including at least one of a value of products or services, and a function to be performed via the instrument, the generating comprising:
receiving an instrument identifier and the data value from a holder of the instrument;
