Aztec Code is an advanced 2D matrix barcode designed for fast, compact, and reliable data encoding. Invented in 1995 by Andrew Longacre Jr. and Robert Hussey, it became an ISO/IEC 24778:2024 international standard. Unlike other matrix codes,

Aztec Code does not require a blank quiet zone, allowing it to store more data in a smaller space. It features a central bull’s-eye pattern that ensures high readability even when printed at low resolution or displayed on digital screens. With up to 32 layers, it can encode thousands of numeric or textual characters while using built-in Reed–Solomon error correction for data recovery. Its robustness and efficiency make it ideal for transport tickets, airline boarding passes, government documents, and commercial billing systems worldwide. Today, Aztec Code is widely adopted by global airlines, rail operators, and public authorities for secure, paperless, and mobile-friendly barcode solutions.wikipedia​ reference:
