ABSTRACT:
A merchant specific debit card verification system which includes a debit card having at least one ID property stored thereon and a merchant's terminal having at least one ID property stored thereon so that the ID property stored on the debit card relates to the ID properties stored on the merchant's terminal in a predetermined manner. The merchant's terminal retrieves the ID properties stored on the debit card so as to provide a retrieved ID property and then transmits to an intelligent network platform the retrieved ID property and the ID properties stored on the merchant's terminal. The intelligent network platform matches the ID properties stored on the terminal with the retrieved ID property and then transmits a validation whereby the debit card may be used at the merchant's terminal.
