I was wondering if anyone knew if it was possible to scann an barcode off o the iphone screen. I recieved a train ticket confirmation via e-mail and need to take the printed confirmation to a kiosk at the station to print off the real ticket. the confirmation has a barcode which gets scanned. The barcode in the e-mail is able to be expanded quite largly and is very clearly on my screen, so it got me thinking if it is just possible to scan the iphone screen. Is the scan able to read a barcode on an iphone screen? I'm not sure how a barcode scanner works, and realize i could just easily print it off and scan it, but thought i would ask.
