ASP.NET QR Code Barcode Introduction
QR-Code is a matrix / 2D (two-dimensional) symbology developed by Denso Wave. It is also known as Quick Response Code, Denso Barcode, QRCode, JIS X 0510, ISO/IEC 18004.
Compatibility: Barcode for ASP.NET control dll is compatible with ISO/IEC 18004 (Second Edition 2006-09-01) bar code symbology specification for QR Code printing. Thus QR Code images generated are readable for all scanners / barcode recognition tools.
Encoding: QR-Code bar code is widely used for its versatility in data encoding, which include: numeric and alphanumeric characters (A-Z, a-z, 0-9), Kanji characters (JIS X 0510), and byte data (default is ISO/IEC 8859-1).
QR Code bar code can encode multiple types of data, including numeric and alphanumeric characters (A-Z, a-z, 0-9), Kanji characters (JIS X 0510), and byte data (default is ISO/IEC 8859-1, including characters from English, German, French, Italian, Spanish, Portuguese, etc.)
