A method of authorizing a debit transaction involves a server receiving from a debit terminal an authorization request message requesting authorization for a debit transaction initiated from the debit terminal. The authorization request message includes a payment credential, a cryptogram and authorization data. The server authorizes the debit transaction without receiving confirmation of authenticity of an identity of an operator of the debit terminal. The server authorizes the debit transaction by confirming that the cryptogram was generated from the payment credential and the authorization data; determining from a database an account number and a default payment amount that is associated with the payment credential in the database, and debiting a financial account associated with the account number by a debit amount equal to the default payment amount. The server transmits to the terminal an authorization response message that authorizes the terminal to release funds in the debit amount.

System and method for authorizing a debit transaction without user authentication

A payment processing method involves a server receiving a payee identifier, and linking the payee identifier to a device identifier identifying a payee device. The server receives from a payor device a payment initiation request identifying a specified payment amount and a payor identifier, links a unique token to the specified payment amount and to the payor identifier, and provides the payor device with the token. The token excludes the payor identifier and particulars of the associated payor. The server receives a payment completion request including the payee identifier and the token, and excluding the payment amount, the payor identifier and payor particulars. The server uses the payee identifier to confirm that the payment completion request was signed with the device identifier, uses the payee identifier to locate a payee account, and uses the token to determine the specified payment amount and a payor account associated with the payor identifier.

Person-to-person electronic payment processing

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.
