Aztec Barcode. History and Purpose
Aztec Barcode is a high density, high capacity barcode. It is a type of 2-D barcodes. Aztec code is able to encode ASCII as well as Extended ASCII characters. Aztec barcode consist of black and white square modules like other 2-D barcodes. Aztec code can encode modules in the range from 15 x 15 to an upper limit of 151 to 151 modules. If Aztec code utilizes its maximum storage capacity of 151 x 151 modules it can encode 3000 characters and around 3750 numerical digits.
AIM, Inc, in 1997 published Aztec code for the first time. Andrew Longrace Jr and Robert Hussey are credited for having designed the initial barcode standard in 1995. The center of the Aztec code is similar in resemblance to the Aztec Pyramid. It is for this reason that this code has been named Aztec barcode.
Aztec is a 2-D barcode. Like other 2-D barcodes, major purpose of developing Aztec code is to provide data encoding mechanism which could encode large amount of data in small area due to high density and which has substantial fault tolerance and error correction mechanism. Aztec code satisfies these requirements.
