Patent ID: 7158947

Claim:
A method for selectively blocking a remote purchase request in which a purchaser attempts to use a card number to make a remote purchase, comprising: providing a memory subsystem for receiving and storing information from a purchase request information set including an origin of the purchase request representing either a telephone number or an internet address, a card number, a requested item identification, a number of requested items, and a cost of purchase; receiving and storing in said memory a current remote purchase request information set; providing a logic subsystem; determining, in said logic subsystem, whether the total cost of purchases in remote purchase requests within a set time period prior to the remote purchase request exceeds a preset threshold total cost of purchases; and if the total cost of purchases from the origin within the set time period prior to the remote purchase request exceeds the preset threshold total cost of purchases, blocking the remote purchase request; or else if the total cost of purchases from the origin within the set time period prior to the remote purchase request does not exceed the preset threshold total cost of purchases, either approving the remote purchase to be made, or performing other tests to determine whether the remote purchase request is to be approved or blocked.
