Abstract

A debit card system replaces food stamps. A photo ID card issued to the food assistance recipient displays an arrangement of numerals that encode and reveal a unique PIN when overlaid by an appropriate mask. The clerk'"'"'s use of the mask to determine the PIN puts the authorized recipient'"'"'s photograph in full view of the clerk for at least several seconds, thereby compelling the clerk'"'"'s unsupervised compliance regarding verification of the identity of the user of the card.

Claims

1. A method of administering public assistance programs for food purchases while eliminating the excessive costs, inefficiencies, fraud and waste associated with food stamps, said method comprising:

issuing to each authorized recipient of public assistance for food purchases at least one card including (i) a recipient identifier encoded thereon, (ii) a photographic likeness of the recipient and (iii) an arrangement of numerals that encode and reveal a unique PIN when overlaid by an appropriate, current mask, with the photographic likeness and arrangement of numerals appearing on the same card;

under the authority of the responsible social services agency, maintaining food assistance recipient account files that reflect the current account balance for each authorized recipient and periodically replenishing each account with new credit according to the prescribed allotment for the recipient;

providing a plurality of masks to each food merchant, each mask being registerable over said arrangement of numerals to reveal a PIN;

under authority of the responsible social services agency, notifying each food merchant on a periodic or random basis of the appropriate, then-current mask to be used in registration over cards to determine PINs during an identifiable period of time;

carrying out each food purchase transaction between a food assistance recipient and food merchant by;

(A) having the food merchant register the then-current mask over the arrangement of numerals on the recipient'"'"'s card to reveal the unique then-current PIN, while compelling unsupervised merchant compliance regarding the identity of the card user versus the photographic likeness on the card and

(B) providing a card processing station at each food merchant location and utilizing the station to input to a banking network (i) the recipient identifier, (ii) the debit charge associated with the purchase and (iii) the then-current PIN for the recipient as determined by utilization of the mask;

approving or declining the transaction by determining the sufficiency of the recipient'"'"'s account balance to cover the amount of the transaction.

2. The method of claim 1 including the steps of processing the transaction between the recipient and food merchant through an existing banking card network, with the banking card network having read-only access to the account file information that is maintained under authority of the social services agency.

3. The method of claim 2 wherein the recipient accounts are periodically replenished with credit.

4. The method of claim 1 including the step of creating profiles of recipient purchase histories to detect fraud or abuse.

5. The method of claim 1 including the step of providing recipients with telephone access to their account balances.

6. The method of claim 1 wherein each recipient is issued a single card containing the encoded recipient identifier, the photographic likeness of the recipient and the arrangement of numerals.

7. The method of claim 1 wherein each recipient is issued two cards comprising a first card containing the encoded recipient identifier and a second photo ID card containing both the photographic likeness of the recipient and the arrangement of numerals.

8. The method of claim 1 including the step of providing a code for entry by the food merchant at the time of a transaction if the merchant determines that the card is being misused or is stolen.

9. A debit/credit card system that compels a merchant'"'"'s unsupervised compliance regarding the verification of the identity of the user of the card at the time of a debit/credit transaction, said system comprising:

a card bearing a photographic likeness of the authorized user of the card and an arrangement of numerals that encode and reveal a PIN when overlaid by an appropriate mask;

a plurality of masks at each point-of-sale location where the card may be used in a transaction, each mask being registerable over the arrangement of numerals on the card to reveal a PIN;

each mask having its own identifier to distinguish it from the other masks, and each identifier being associated with a time interval during which its respective mask is authorized to be used to determine the unique PIN for that time interval;

whereby the merchant must overlay the card with the then-authorized mask to determine the unique PIN that is necessary to authorize the transaction and in so doing has the photographic likeness of the authorized user of the card in full view for a period of at least several seconds.

10. A debit card system for use with existing electronic credit/debit card computer networks to facilitate food purchase transactions by authorized recipients of public assistance for food purchases, said system serving as a preferred alternative to the use of food stamps and comprising:

a card bearing a photographic likeness of an authorized recipient of public assistance and an arrangement of numerals that encode and reveal a PIN when overlaid by an appropriate mask;

a plurality of masks at each point-of-sale location where the card may be used in a transaction, each mask being registerable over the arrangement of numerals on the card to reveal a unique PIN;

each mask having its own identifier to distinguish it from the other masks, and each identifier being associated with a time interval during which its respective mask is authorized to be used to determine the unique PIN for that time interval;

whereby the merchant must overlay the card with the then-authorized mask to determine the unique PIN that is necessary to authorize the transaction and in so doing has the photographic likeness of the authorized user of the card in full view for a period of at least several seconds.
