I remember in 2007 there were a few people getting very excited about QR codes, which are special bar codes that can be read by mobile phones and such like. They were predicting they’d be in magazines, on posters, t-shirts… all over the place. We were all meant to be scanning these codes to link to offers on the Internet, read details about new products and all sorts of things.
Well, the other day, I noticed the enthusiasts had got one of their predictions right. QR codes are appearing on posters, but perhaps not in the way they expected.
