Abstract: Hereinafter disclosed is methodology and apparatus for optically reading, or recognizing, numbers on such articles such as credit cards and the like. According to one illustrative embodiment of the invention a credit card having an identifying number, or account number, consisting of a plurality of decimal digits is illuminated by a source of light. Reflected light from the face of the card is directed through a lens and projected on a mask which has a plurality of unique hole patterns therein. The light reflected from the digits on the card is considerably darker than the light reflected from other portions of the card. There is provided in the mask an individual pattern, or array, of holes for each digit''s reflected light. Each hole in each pattern of holes has associated therewith a photodetector. Hence, each pattern of holes has a corresponding pattern of photodetectors. For each of the decimal digits 0 through 9 on the card a unique pattern of illuminated and nonilluminated (or light and dark) photodetectors results. This unique pattern, or array, of light and dark photodetectors provides a unique set of signals which are representative of the particular decimal digit whose light has been reflected on the hole pattern in the mask. Ultimately, sets of such signals representing all the decimal digits are delivered to a comparator for the purpose of determining whether or not the number on the credit card corresponds to a like number stored in suitable storage means; said stored number also being delivered to the comparator.
