The supermarket of the future? I’m not even sure where to begin with how stupid some of that stuff is. How is using your mobile to self scan barcodes any easier than letting people use purpose made barcode scanners? I know some supermarkets tried that a while back and did it revolutionize shopping? Nope. God help you if your battery dies before you get to the checkout….
If they are using RFID tags on food, why not just tag everything so that you’re whole trolley is totaled up as you walk through the till?
I do like the wine tasting idea however.
