1. In combination, a code and code reading system:

  • said code comprising some 200 by 200 dots printed in at least five contrasting colors on a record medium in at least one data field;

    said reading system comprising a scanning head adapted to be immoveably placed over and overlay said entire at least one data field, with no relative movement between said scanning head and said at least one data field as it is read;

    said scanning head including activating means and means for sequentially flashing light upon said entire at least one data field to sequentially obtain data from said 200×

    200 dots printed thereon in said five contrasting colors;

    said sequentially obtained data being recorded on an image recording means held in said scanner head;

    means to feed said recorded image data to a random access memory (RAM) of a microprocessor to form a replica of said entire data field read and the distribution of the contrasting color dots printed therein, said replica of said data field being stored in said RAM until a predetermined number of sequential scans have been completed; and

    decoding means in said microprocessor whereby said replica of said field in said RAM may be manipulated to perform assigned functions.
