SYSTEM AND METHOD FOR AUTHORIZING A DEBIT TRANSACTION WITHOUT USER AUTHENTICATION

摘要

A method of authorizing a debit transaction involves a server receiving from a debit terminal a message requesting authorization for a debit transaction. The message includes a credential provided by a payment token interfaced with the debit terminal. The credential is uniquely associated with the token. The server is in communication with a payment definition database that associates a plurality of payment credentials each with a respective financial account and a default payment amount. The server determines the financial account and the default amount by querying the database with the received credential. Particulars of the determined financial account and default amount are indeterminable from only the credential. The server authenticates the message and facilitates a debit in the default amount from the financial account. The server performs the receiving, determining, authenticating and facilitating all without confirmation of authentication of a bearer of the token.
