Network and method for clearing point-of-sale terminal pre-authorizations

Abstract:

A clearing network includes a server, a POS terminal, and a computer network interconnecting the server and the POS terminal. The sever is configured to receive account numbers over the computer network, determine that an occurrence of one of the account numbers in the plurality of account numbers exceeds a maximum limit, and via the computer network update the pre-authorization database with the account number. The POS terminal is configured to receive a pre-authorization request that includes an authorization amount and the account number, query the pre-authorization database with the account number, and after locating the account number in the pre-authorization database from the query (a) confirm that the authorization amount is not greater than an authorization threshold, and (b) without generating an online authorization request, save in a clearing database an authorization confirmation message that includes the account number and the authorization amount.
