Aztec Code is a two-dimensional barcode that encodes information in a square pattern. It was developed in the late 1990s and is designed to store large amounts of data in a compact format. The code can be scanned using a camera or a barcode reader, making it useful for various applications, including product labeling and ticketing. One of the key features of Aztec Code is its ability to be read even when partially damaged or obscured. It is often used in mobile applications, such as boarding passes for airlines, where quick and reliable scanning is essential. The code can hold different types of data, including text and URLs.
