I'd imagine it's similar to the heuristic Amazon uses today with their A-Z Customer Guarantee.

If you request a lot of refunds for a single trip, or have a history of requesting refunds, your individual risk score goes up, and the hoops you jump through to get a refund increase.

Also for retail grocery stores now, loss prevention is already an issue.

Right now, a person can take an item off the shelve and hide it, leaving only security cameras and human personnel to watch for theft.

Adding in amazon's technology would be additional layers of defense.

How does amazons tech add defense? You still need human personnel to do anything about theft. People shoplifting don't care if the door is beeping while they walk out and disappear.

Without amazon tech, you take an item off the shelf, hide it, and leave. There are cameras with loss prevention staff monitoring the feeds, and in some stores, sensors that trigger an alarm upon leaving.

With amazon tech, in addition to manually monitored cameras, you add AI monitored cameras, and sensors on shelves to detect an item has been taken.

Without Amazon's tech stores rely on staff members witnessing the item being hidden.

With Amazon's tech, the item is taken and marked for payment as soon as it's removed.
