This is one of the geekiests supermarkets I've ever seen! A German supermarket is inviting customers to use their mobiles cameras to scan the product bar codes and check out without the help of a cashier. Trust on the customer seems to be a key point of the model...
Interesting enough RFID technology was not chosen, preferring good old bar coding. In my experience, reading barcode on the mobile introduces new problems - low quality cameras, scratches on lens or low quality display just don't help.
Check it out: "Future Store".
