QR codes are encoded codes for easy data access. Anyone can generate personal QR codes online. QR codes are direction-agnostic and store large amounts of data. QR codes use quiet zone and three squares for alignment
Data Matrix is a two-dimensional barcode using black and white square modules. Symbols can hold up to 1556 bytes or 3116 digits. Each dot represents a bit, with black dots typically representing 1. Supports up to 16 symbols in structured append format
Data Matrix is a two-dimensional bar code represented as dark/light dots with finder pattern. Symbols can be square or rectangular, with mandatory quiet zone around them. Finder pattern defines shape, size, and orientation of the symbol
Barcodes were invented by Norman Woodland and Bernard Silver in 1952. Initially used parallel lines, later evolved into two-dimensional matrix codes. First successful supermarket checkout system implemented in UK in 1972. UPC barcode standard adopted by NAFC in 1973
Code128 is widely used due to full ASCII support and high density capabilities. Supports three variations: A, B, and C with switchable control characters. Includes Auto mode for automatic data detection and variation switching
GS1 DataMatrix is a two-dimensional barcode with dark and light dots. Symbol consists of finder pattern defining shape and orientation. Mandatory Quiet Zone surrounds symbol with constant width equal to X-dimension. Symbol always has even number of rows and columns
