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.
