Device for selectively blocking remote purchase requests

摘要

A system for selectively blocking a current remote purchase request based on information gained from at least a previous remote purchase request. The device includes a first data input subsystem capable of receiving purchase request information set including a credit card number, merchandise descriptions and origin. A memory subsystem receives the information set from the previous and current remote purchase requests. A logic subsystem compares the purchase request record of the current remote purchase request with the purchase request record of the previous remote purchase request and automatically blocks the current remote purchase request if the comparison meets any one of a predetermined set of criteria. At least one criterion includes a condition that the current purchase request origin match the previous purchase request origin.
