HCC2D Decoder vs Gift Cards Now

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 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.

Gift Cards Now is a simple wallet for the gift cards you already have. No account, no cloud service — everything stays on your device. SCAN INSTEAD OF TYPING Point your camera at a physical gift card and the built-in scanner reads the card number, PIN, and any barcode straight off it, using Apple's on-device text and barcode recognition. Review what it found, tap to copy, or save it straight into your wallet. ONE WALLET, EVERY CARD Add a merchant name, balance, card number, PIN, and expiry date for each card. Every card gets its own wallet-style view, and a scannable barcode is generated for showing at checkout. NEVER LET ONE EXPIRE Set an expiry date and get a reminder seven days before the card runs out, so a forgotten card doesn't quietly become worthless. FIND A BETTER DEAL The Discover tab links out to a few well-known marketplaces (for buying gift cards below face value) if you want to add funds for less. PRIVATE BY DESIGN Your cards are stored only on this device. There's no login, no account, and nothing is uploaded anywhere — scanning happens entirely on-device.
