Via we make money not art and Engadet comes ColorCode – apparently a success in South Korea, and are about to be introduced in Japan – which seems like more of a tinyurl.com for cellphones, developed by ColorZip Media.
Although the colour may make it more visible, appealing, I think the fact it is only a tinyurl like link to one companies server, and requiring the connection to the server for any functional make it less value add, and more proprietary lock in.
More info on QR Code, plus I’ve blogged about QR (two-dimension quick response codes), starting a year ago, in TokyoArtBeat and QR codes; One Fish, Two Fish, Red Fish, BarCode Fish…; Camera Phones Link World to Web; and Camera-phone barcode reader
April 26th Update: Gizmodo has a cute piece on someone doing creating a QR Code using white and dark chocolate as explained in qrcodeblog, a blog in QR codes. Plus RFID in Japan describes an attempt to encode a QR Code message on Bento using Nori (toasted seaweed) and rice: “Nori for the age of information technology”??
