Method for selectively blocking remote purchase requests
View Patent ↗A method for partially verifying the legitimacy of a remote purchase request based on a card number from a card issuing financial institution. The method includes receiving and storing a first purchase request information set including an origin and a card number. Further, the origin and the card number are sent to the card issuing financial institution to determine if the origin matches an origin on file for the card number at the card issuing financial institution.
1. 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.
2. The method of claim 1 , further comprising:
the total cost of purchases from the origin within the set time period includes the cost of the remote purchase request.
3. The method of claim 1 , wherein a merchant delivers remote purchase requests to a card issuer for approval and processing, further comprising:
the step of determining being made prior to delivery of the remote purchase request to the card issuer; and
the step of blocking further comprises the step of blocking the remote purchase request being delivered to the card issuer.
4. The method of claim 1 , further comprising:
determining whether said origin is a public or semi-public telephone; and
blocking said remote purchase request if said origin is a public or semi-public telephone.
