| titleOfInvention | Method and apparatus for operating authorization control systems |
| abstract | A method and apparatus for serially reading non-ferrous hidden coded indicia on opaque cards has a single row (or staggered row) of sensors. These sensors and related circuitry detect the presence or absence of thin copper discs (bits) arranged in rows and columns and encased within the opaque card material. The rows of coded indicia are movable at right angles to the sensor row(s) thereby allowing the sensors to detect the bit presence in each row and to serially transmit data (corresponding to the bit presence) via a single line transmission technique to a data processing console. The data may take the form of BCD information and a determination is made at the data processing console (or in the reader unit itself) as to the correctness of same for the purposes of access, dispensing or the like. A decoding section, including a multiple correct code matrix and a combination correct digit counter and a total digit counter check either (or both) the card data or push button data for correctness. The method includes steps of CAUSING RELATIVE MOTION BETWEEN A ROW OF SENSORS AND A CARD HAVING HIDDEN CODED INDICIA THEREON IN THE FORM OF NONFERROUS BITS ARRANGED IN A PLURALITY OF ROWS AND ENCASED THEREIN, SERIALLY DETECTING THE PRESENCE OR ABSENCE OF SAID BITS IN SAID ROWS, PRODUCING AN ELECTRICAL OUTPUT HAVING SERIAL DATA THEREIN THAT CORRESPONDS TO SAID PRESENCE (OR ABSENCE) OF SAID BITS IN SAID CARD ROWS, AND DETERMINING THE CORRECTNESS OF SAID CODE REPRESENTED BY SAID ELECTRICAL OUTPUT. |
