|Long Description||Signs, and especially symbols, are representations often of the abstract rather than the literal, which allows for a much broader interpretation of their meaning. A look at any dictionary will tell you what they are, but here we ask why and how they came to exist. Here we look for reasons why so many of us are visually illiterate, and why we no longer understand the symbolism which communicated stories and information to our forebears. We also see how symbols have changed with time, and how they have been manipulated to make them encapsulate new meanings.|

Identified by the bulls-eye pattern in the center of the square, the Aztec Code barcode is easy to recognize. This symbol supports patterns ranging from 15x15 up to 151x151 blocks with one special rune that can encode a single byte. This rune is 11x11 blocks.
The bulls-eye is either 9x9 or 13x13. The ring directly beyond the bulls-eye is the mode section. The remainder of the symbol is the data and error correction. Three of the corners of the core hold the orientation markers. In the image below we have marked the bulls-eye in red, the mode section in green and the orientation markers are in blue leaving the data area in black and white.
The data is stored in pairs of rings that stretch out from the core. The decoding of data starts at the orientation marker made up of three blocks and procedes in a counter-clockwise direction. There is no outer marker to identify the outer boundry because the size is encoded in the core.
Because this symbology is mainly used in industry and not for public consumption, most smart phones can't read them. Try with your smart phone.
Although we don't have a generator here on our site at the moment, there is one availbale at www.racoindustries.com if you wish to create your own Aztec Code barcodes.
