ABSTRACT:
A method, system, program, and method of doing business are disclosed for electronic commerce that includes the feature of a “thin” consumer's wallet by providing issuers with an active role in each payment. This is achieved by adding an issuer gateway and moving the credit/debit card authorization function from the merchant to the issuer. This enables an issuer to independently choose alternate authentication mechanisms without changing the acquirer gateway. It also results in a significant reduction in complexity, thereby improving the ease of implementation and overall performance.
