I haven’t had any luck with getting any hard numbers about click-throughs for the local QR campaign run by Mohawk, but coincidentally, a report on QR code activity (PDF) has been made public and I found out about it through this article about using QR codes in social media. RWW then published an article today claiming that barcode scanning (both traditional and 2D QR type codes) are up 700%. While that’s interesting, it’s not indicative of whether this is a real trend or marginal activity. If activity is only at 1% of the population, an increase of 700% is not necessarily significant (7%). The quote towards the end of the article does note “80% of US consumers surveyed expressed interest in scanning mobile barcodes”. Again, that’s within the Android marketplace, which may be skewed towards consumers who are technologically early adopters. It is significant when you start to tie all these loose ends together – there clearly is a trend developing where people are using barcodes and QR codes to link real objects to virtual information. Those that are not doing this now are at least interested in doing this in the future. Now, what will be the killer app for this sphere?
