High Capacity Color Barcodes (HCCB) and JAB Code are advanced 2D barcode technologies that use multiple colors to significantly increase data storage density compared to traditional black-and-white codes.

HCCB Technology Developed by Microsoft Research, HCCB uses multicolor symbols and unique shapes to store more data per square inch. Laboratory tests have shown storage of up to 2,000 bytes or 3,500 characters per square inch at 600 dpi — roughly equivalent to two pages of a novel. It supports digital signing using Elliptic Curve Cryptography (ECC) with RSA-1024 equivalent security, enabling data integrity verification. HCCB can store multiple payloads in a small file system format and is optimized for mobile device decoding, even from low-quality images, outperforming QR Codes in some scenarios.

JAB Code JAB Code (Just Another Barcode) is an ISO/IEC 23634:2022 standard for high-capacity color barcodes. It uses colorful square modules arranged in grids, with a primary symbol (containing finder patterns) and optional secondary symbols for scalability. It supports error correction and can encode from small to very large datasets. JAB Code is open-source, with a C-based library for encoding/decoding, and can be built for Linux or Windows.
