I think you are missing the point.

You still walk into the store, and pick the items you want and place them in your cart. No one is forcing you to get the expired milk or rotten vegetables.

The system just knows what you put in your cart and charges you for it automatically. It is just designed to eliminate the requirement to have people manning check out counters.

But how does it know what's in your cart? Sensors on the shelves? RF chips inside everything? Are you matched to your cart, or do they have door scanners that just scan everything when you leave? What if two people leave at the same time? What if you have something in your cart, but put it back/on a random shelf later?

A lot of grocery stores/hardware stores have put in the self-checkout lanes. They are really annoying and buggy and I hate using them. Avoid it everytime I can.

There is still a problem with it. Currently, punks will take security tags from packages, and place them in or under carts. When a customer walks out through the security sensors, alarms go off and it embarrasses the customer. Punks get their laughs.

Only now, with this new system, the customer gets falsely charged for the punked tags with no merchandise. Customer has sad face when they review the charges later on at home.
