It's not a camera phone, but think of the PWC possibilities if vending machines had barcode scanners attached to them.
PWC Vending Machine
Right now, the machine has attached to it a barcode scanner, a fingerprint reader, and a web cam for facial recognition.
Want a Coke? Stick your thumb on the reader so the machine recognizes you as having an account, take out the drink, scan it with the barcode reader, then walk way, never having had to reach into your pocket for change
The project, called SodaVision (sodavision.com), is the brainchild of UCSD engineering associate professor Stefan Savage.
