I’ve been surprised by the response to my previous post on QR-codes – the 2-d barcodes that can be read by mobile phones.
I’m still skeptical, but Roger, the editor of http://2d-code.co.uk/ wrote to point me at the impressive Japanese experience with QR-codes – apparently 51% of Japanese mobile phone users use the barcode function.
Looking through his site, I liked the idea of linking the QR-code to a mobile facebook page and was inspired by this Harrods ad to create a QR-code for a Twitter sign-up SMS. Here are examples of each:
Another option is that QR-codes may be used for the VCF files used to exchange addresses between phones. This article suggests linking to one of these files on a website – but I’m not entirely clear why you wouldn’t just put the whole address file into the QR-code as follows?
Funny you should be looking at these right now. Japanese people can even put them on their gravestone.

While I remember, there’s a nifty Javascript QR code decoder at http://www.hafenscher.net/qrcode/qrcode.jar
