HCC2D Decoder
This app allows you to scan and decode HCC2D and QR code symbols using your mobile camera. It is based on advanced research in high-capacity barcode technologies and provides reliable decoding.
Key features:
* Decode HCC2D color barcodes.
* Full support for standard QR codes.
* Real-time scanning using the camera.
* Robust detection and error correction.
* No ads and no registration required.
HCC2D is a color two-dimensional barcode format that increases data capacity compared to traditional QR codes while preserving their structure. By using multiple colors, each module can encode more information, enabling higher data density in a compact symbol.
HCC2D codes can be generated at: hcc2d.com
The app captures images, detects barcode regions, corrects perspective distortions, and analyzes color or intensity patterns to reconstruct the encoded data.
Notes:
* Low-quality color printing may reduce decoding performance.
* Best results are achieved with screen-displayed or high-quality printed codes and a high-resolution autofocus camera.
* One-dimensional barcodes are intentionally not supported.
