  • (a) a data input subsystem, connected to a data line, capable of automatically receiving an origin, and of further receiving a card number and merchandise descriptor to form, in total, a purchase request information set;

    (b) a memory subsystem adapted to store said purchase request information set; and

    (c) a logic subsystem adapted to effect a comparison of a said purchase request information set, including a listing of a first card number, of a said current remote purchase request with a said purchase request information set of at least a said previous remote purchase request, including a listing of a second card number that is different from said first card number, and adapted to automatically block said current remote purchase request if said comparison meets any one of a predetermined set of criteria wherein at least one criterion includes a condition that said purchase request origin of said current purchase match said purchase request origin of said previous purchase request.
