You know food prices have been coming down over the last year or so? Keep finding ways to sell food cheaper, it will keep getting cheaper to buy.

The argument is, in the future things will cost almost nothing to supply, so will cost almost nothing to use. For food this wont be as easy, but other things I guess could head this way in 50 years or so.

How will it handle this:

Pick up item x, walk a few aisles then decide you don't want item x anymore. Dump item x on a random shelf and continue your business.

I would imagine those big sensors you walk through are RFID readers which compare virtual receipt and actual contents of bag. That's how I would do it.

I wouldn't have thought location matters too much, the system should be able to recognise the item so the fact you've moved is a bit meh... otherwise there would be issues in a more common case where you're stood next to the part of the shelf where two product lines join.

Though on a related issue - what happens if a kid grabs an item... do the kids get tracked when going into the store along with the parents or is it just the items that are tracked.

If only there was a video that explained everything. Granted it's not in excruciating detail, but what do you think the recognition and "deep learning" stuff is for? :)

RFID chips needs to be within an inch of the reader to work.

No they don't.

There are various different types of tag grouped under the RFID banner including active and passive ones and various different wavelengths within each of those which can give read ranges up into the meters.

The end of the checkout girl.

You will be telling your grandkids, "Back in my day a human being had to scan a printed code on every item with a laser beam.....by hand! This was before you could put it in a bag and pay for it with money made from real paper and metal. But then this was in the days when we still had to choose different foods to eat, we didn't have nutrocell implants you could set to any flavour you want from your phone".

The RFID tags used on products are not active, thus need to be within an inch of the reader.
