Abstract:
An information storage apparatus for storing information on inserted cards said apparatus comprising:sensing means for sensing printed patterns on the surface stored on said card, said patterns arranged in a predetermined number of possible active areas of said card;decoding means for decoding said sensed printed patterns into corresponding data;printing means for printing dot patterns on said card in at least one of said active areas;positioning means for positioning said sensed card at known locations relative to said sensing means and said printing means;wherein said sensing means is adapted to sense the printed patterns in a current active printed area of said card, said decoding means is adapted to decode said sensed printed patterns into corresponding current data and, when said current: data requires updating, said printing means is adapted to print said updated current data at a new one of said active areas after activation of said positioning means for correctly position said card.
