The thread is a little old. But I also need some help on generating barcodes.
I want to ganerate my own barcode for my stuffs, and I need a barcode library to record the infomation encoded in their own barcode. I ggoogled, but only to find a fine QR code generator and a Data Matrix code generator. I don't know the difference and which one to choose. Could anyone help?
Thanks in advance.
QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobile phones with a camera, and smartphones. It consists of black modules arranged in a square pattern on white background. The information encoded can be text, URL or other data. In detail, QR Code can encode: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; or other sets as otherwise defined); Kanji characters. Kanji characters in QR Code 2005 can be compacted into 13 bits.
While data matrix can encode:values 0-127 in accordance with the US national version of ISO/IEC 646; value 128-255 in accordance with ISO 8859-1 (referred to as extended ASCII).
