I'm talking about QR codes, square barcodes that connect mobile phones directly to a webpage.
This is one of many code generators availiable. You type in the page to be accessed and it makes a code.
A label with a BC logo and a BCID specific QR code (which goes to the relevant journal page) would be a great addition to my bookcrossing arsenal.
So, is anyone else going to be putting these codes on books too?
