Anyone know which standard Blackberry Messenger 5 uses?
There are 3 standards.
October 1997 � AIM International
January 1999 � JIS X 0510
1 September 2006 � ISO/IEC 18004:2006 Information technology � Automatic identification and data capture techniques � QR Code 2005 bar code symbology specification
It uses Google's ZXing 1.3 library. The library itself supports multiple barcode formats, but I'm not sure which of the QR standards are built into that.
