Abstract
A machine-readable matrix-type code has either repeated or non-repeated dot patterns in one direction representing digital characters which are read by a sensor moved in a direction which is generally normal to the patterns. The patterns of the code may be formed in a manner wherein the sensor views a portion of repeated patterns, or the code may be of lesser magnitude wherein the entire non-repeated pattern area is covered by the field of view of the sensor.
