Once Card Number Generation and Validation Method and Apparatus

[Category : - Indentification and payment methods]
[Viewed 431 times]

A once card transaction system comprises a once card embedded with a once card number generator. The embedded once card number generator is able to communicate a once card number with a swipe card reader through the magnetic stripe emulator interface on the back of the card for in-store transaction or display it at the front of the card for online transaction. The embedded once card number generator is capable of generating an unpredictable once card number inside the once card without communicating with a central server. This distributedly generated once card number can be approved by an authentication entity by a valid OCN hashing list, and once the number is transacted, it is put on a rejection list.
