QR Code, or Quick Response Code, is one of the most popular 2D barcodes available today and is used in a variety of industries including commercial tracking applications and mobile phone tagging applications. QR Code offers more data storage than linear (1D) barcodes, up to 2,953 bytes, 4,296 alphanumeric or 7,089 numeric digits, and includes an Error Correction Code (ECC) for error-free reading even when a symbol is partially lost or destroyed.
