Aztec codes are 2D barcodes invented in 1995, utilizing technology that allows reading in multiple directions and offering features like high data capacity and error correction. While they include support for all ASCII characters, they have limitations such as difficulty in decoding and a lack of support for certain character sets. These barcodes are commonly used in sectors like transportation for electronic boarding passes and other applications like invoicing and mobile payments.

11. How Does An Aztec
Bar Code Work?

12. A pattern of various layers surrounds
the core square in a barcode Aztec style.
These squares are put together to
encode the information the Aztec
barcode contains.
The "quiet zone" feature of other codes
is not required.
