A US inventor has showcased a supermarket shelving system that does away with checkouts and cashiers.
Perplexed at the constant queueing and waiting in supermarkets this inventor has come up with weight sensitive shelves that record your purchase as you take items from the shelf. Once you have completed your shopping list, you simply walk out of the store. Your purchases are recorded using radio frequency and tap-n-go type technology linking with your credit card or mobile phone.
Prices are shown on digital displays at the front of each shelf which are centrally updated and stock is replaced automatically. Not something we are likely to see in market stalls in the near future but an interesting concept nonetheless.
