QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed.
OnBarcode provides several QR Code Generator components and software, including
QR Code C#,
QR Code .NET,
QR Code Java,
QR Code VB.NET,
QR Code ASP.NET,
QR Code iPhone,
QR Code iPad,
QR Code Generator.
Android QR Code Generator Valid Data Scope
Android QRCode Generator supports:
- numeric data (digits 0 - 9);
- alphanumeric data (digits 0 - 9; upper case letters A -Z; nine other characters: space, $ % * + - . / : );
- byte data (default: ISO/IEC 8859-1);
- Kanji characters.
