Last week, Microsoft launched Windows Live Barcode, bringing Denso’s two-dimensional, ‘quick response’ QR Code format to the Windows Mobile platform. The service consists of two elements:

- Online tools to generate contact cards or notebook entries (450 character limit).
- A mobile ’scanning’ application to read QR codes into a Windows Mobile handset (this doesn’t seem to be available from the site).

I’ve long thought the potential of 2D codes, like QR, Semacode and others, was enormous - but very few handsets are equipped, by default, with the capability to scan codes. Consequently, we see very few codes embedded in online services or the physical world. Microsoft’s move could help to kick start code usage…

I have a niggling feeling that there’s a compelling intersection of microformats and 2D codes. I wonder if LinkedIn, Upcoming, Flickr and other personal publishing service began to display their microformatted data as 2D codes, whether we’d see a corresponding uptick in code support on handsets…are 2D codes the enablers for mobile microformats?
