And once they hear Amazon can't track a lot of people moving quickly... A lot of people will decide to start moving quickly.

I can already foresee a dozen people showing up in zebra-striped hoodies to see what happens when they shop together.

Time for some "identical twin" experiments.

Yes. You need to have the Amazon Go app installed on your phone, and you scan your phone at what looks like a turnstile to enter the store, from the store's PR videos. Then the store keeps track of what you pick up using computer vision, your phone and various sensors, and charges everything you walk out with to your account. Unless you can avoid the requirement to load an app and scan it to get into the store, walki…

So children are not allowed in the store? What's stopping someone from just stuffing their kid full of high end goods and asking them to wait in the car?

The same thing that stops people from doing that in a regular store? Mostly good morals backed up with cameras and the occasional security guard.

I wish more companies would delay their products due to quality concerns. It shouldn't be viewed as a bad thing.

To be fair, this quality concern mostly affects Amazon. I don't imagine too many shoppers would complain about being undercharged. Though it is possible the reverse could be a problem as well (and that would not be something Amazon would highlight).

In a nutshell: Their tech can't track items if there's a lot of people or fast movement.

And once they hear Amazon can't track a lot of people moving quickly... A lot of people will decide to start moving quickly.

A lot of people will turn up to play basketball, while someone in a bear suit steals things.

All it takes is a loss factor of a few percent, and the entire model breaks down.

This is the same reason that long-range RFID (UHF RFID) never worked for cashierless checkout too. You couldn't ensure 100% coverage. Some tags just couldn't be read -- either due to adversarial tactics (eg. shielding with your body) or material properties (eg. metal) -- and the engineering countermeasures to overcome these challenges made the tags too expensive for low-margin goods.

They realize that amazon now measures the height of each customer, also has a miniature drone following them around and each floor tile measure the weight of the people for that extra data point, oh and some have employees disguised as customers whom help the system when in doubt.

Weight belts, got it.

I am an identical twin and on my brothers surface book I'm able to fool windows hello for some reason.
