Amazon claims cameras automatically track what you take and put back. But if that's the case, then I'm left confused as to why receipts take so long (15-20 mins+ sometimes) to be generated after leaving the stores?

Is it possible it's actually a manual process of people watching the videos, or more likely identifying what happened at each "take off shelf/put on shelf" point?

They're still just building up the customer base, training data and models and it's not as magical as it all seems?

Is your observation based on multiple samples? Or just a couple of casual visits? Would be interesting to know their real median receipt generation time.

They need to wait till not only you leave the ship, but also all people who were near you when you picked or returned any item. Then they can use that to resolve ambiguities ("one of these 3 people took this item which is now missing from the shelf, who was it")
