Common Technical Resolutions
EAN-13 / UPC-A Check Digit Issues
If your barcode data contains 12 digits for EAN-13 or 11 digits for UPC-A, CURL.LY Offline computes the final Modulo-10 check digit automatically. If you provide all 13 digits, the app validates whether the 13th digit matches the mathematical standard.
High-Density QR Code Scanning
Large vCard 3.0 records or multi-paragraph texts create Version 10+ QR matrices with small modules. When displaying on screens, increase brightness or export as 1024x1024 PNG for optimal optical camera capture.
Wi-Fi WPA3 Compatibility
CURL.LY Offline adheres to the universal ZXing standard (WIFI:T:WPA;...). Modern iOS (15+) and Android (10+) devices natively interpret this format for WPA, WPA2, and WPA3 Personal networks.
