AUTHORIZATION CONTROL NETWORK AND METHOD OF VALIDATING AN AUTHORIZATION REQUEST

Abstract:

An authorization control network includes at least one computer server. The server(s) receives a cardholder credential and a profile modification request from a communications device, and determines an account attribute by querying a profile database with an account identifier. The server(s) rejects the modification request if the server determines from the account attribute that a limit profile associated with the account identifier is linked to a cardholder credential other than the received cardholder credential. The server(s) then receives from a POS device an authorization request that includes the account identifier and an authorization value. If the server(s) determines that the authorization value does not exceed a limit value saved in the limit profile and does not exceed a credit amount associated with the account identifier in a transactions database, the server(s) generates an authorization response confirming authorization of the authorization value, and transmits the authorization response to the POS device.
