really doesnt sounds awesome to me... How do you steal then ? :)

it would be awesome in a society in which you dont have to pay for your needs

and where electricity is free and clean...

Wie liest man denn da Inhaltsstofflisten? Wie fühlt man das Material der Verpackung? Wie erriecht man, ob einem der Weichspüler gefällt? Und die Überwachung ist wohl inklusive - das funktioniert wohl nicht ohne irgendeine Personenzuweisung wie bei RFID.

Gimmick. You then need two people to pick items, you still need to restock shelves, the whole experience may get slower, and one might generally be better off ordering food online (as we do in the UK), where the same limitations apply except you don't have to walk around, just search.

And what about selecting? If you asked for milk and it has expired... or if you ask for fuits and it's green?

Not seing what you're buying is a disadvantage for you!

I'd tap that. :-D
