Abstract:
1. A method for integrating proximity payment card transaction parameters for a payment-by-proximity-card transaction in industry standard -ISO 7811-formatted magnetic card data structures, wherein said magnetic card data structures comprise industry-standard Track 1, Track 2 and Track 3 magnetic card data structures, such that said proximity payment transaction parameters are in a format compatible with an electronic payment system infrastructure for processing magnetic stripe card payment transactions, the method comprising the steps of: (a) providing in a data field on a proximity payment card a static bitmap which identifies unused positions in a discretionary data field of said magnetic card formatted data structure associated with said proximity payment card; and (b) contactlessly transmitting said bitmap to a proximity payment terminal for placing said proximity payment card transaction parameters in the discretionary data field of said industry standard magnetic card formatted data structure at positions identified by the bitmap, the resulting electronic proximity payment transaction processing message generated by said proximity payment terminal using said bitmap is in a standard magnetic stripe format compatible with electronic payment system infrastructure for processing magnetic stripe card payment transactions and so that the payment-by-proximity-card transaction is processed by said electronic payment system infrastructure as if the payment-by-proximity-card transaction is a standard magnetic stripe card payment transaction.
