Abstract:
A computerized method for generating a time-limited number for use in a payment card transaction involving a payment card issued to a user by a financial institution. The payment card comprises an original payment card number. The method comprises the steps of providing to a processor a first plurality of digits of the original payment card number, where the first plurality of digits are predetermined digits associated to the financial institution, providing to the processor a desired expiration date through which the time-limited number is valid for acceptance in the payment card transaction, and executing a program by the processor so that the program sets a first plurality of digits in the time-limited number to the first plurality of digits in the original payment card number, generates a first number corresponding to the desired expiration date, sets a second plurality of digits in the time-limited number to the first number, and outputs the time-limited number.
