Description by Marco Querini Written by the developer, not by AppBrain. Click to read.
Key features:
* Decode HCC2D color codes.
* 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 code 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.
The app captures images, detects barcode regions, corrects perspective distortions, and analyzes color or intensity patterns to reconstruct the encoded data.
To transfer files from a desktop computer to your smartphone via a stream of HCC2D codes, use HCC2D Decoder together with the HCC2D Streamer desktop companion app.
Notes:
HCC2D codes can be created using the official online generator at hcc2d.com, the HCC2D Encoder application, the open-source CLI encoder, or the Debian/Ubuntu packages provided through the official HCC2D APT repository.
* 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.
