Authorization control network and method of validating an authorization request

Abstract

An authorization control network includes a limit profile database and at least one computer server. The server(s) receives an account identifier and a datum from a communications device, and associates the datum with the account identifier in a limit profile record of the limit profile database. The server(s) also receives the account identifier and a transaction limit, and associates the transaction limit with the account identifier in the limit profile record. The server(s) then receives from a POS device an authorization request that includes the account identifier and an authorization amount. If the server(s) confirms that the authorization amount does not exceed the transaction limit that is associated with the account identifier in the limit profile record and does not exceed an available credit limit that is associated with the account identifier, the server(s) transmits to the POS device an authorization response that confirms authorization of the authorization amount.
