Altercode is a quick and simple QR-Code reader ; no redirection, no advertising. It's able to read QR-Codes and many other barcodes Formats, but it's optimized for Altercodes, which are Accessibility-Oriented QR-Code : when you see an Altercode, you know that by flashing it you'll be able to access alternative ways to get informations about the document the Altercode is inserted in. For example numeric document, audio version, ASL or foreign languages version etc.
Altercode is powered by ZXing, many thanks to them.
