I'm just playing with the QR Code system and I was wondering if anybody else is using it, and if so, have you got it to work when etched into glass.
Most smart phones can read the QR Code either off a screen or a printed page and present the decoded information. I can get the code to work fine when printed on to paper, but I suspect that there isn't enough contrast when etched onto glass.
For those that don't know about QR Codes (do a google for: wiki QR_Code). There are lots of free QR Code generators out there (do a google for: qr code generator) that will encode stuff like urls, text, phone numbers, etc, into the 2 dimensional barcodes.
As an example, this is the QR Code that decodes to my web site. It works fine when printed as small as a 1/2" square graphic.
