So, is it me or has interest in QR Codes just been punted into the fore? Clearly, when a service provider like Facebook adds this functionality (Facebook Kicks Off Implementation Of QR Codes), then it is going to have an impact in usability.
I don't know the legal situation with the use of QR codes in the US. Neomedia represents the IP owner with the most clout - justified or not. However, once again, they appear to be in trumpoil.
