Whoa, at first I thought "Interesting concept" but by the time I read

"allowing them to see the total of their purchases before they reach the register"

a DING went off in my head. This is definitely the future! Amazon Go and whatknot; people want to save time. Time is money. It would feel more right for the customer to scan the items as they collect them rather then collect items then have the items re-collected by a cashier at the end.

This is especially relevant in california where they banned plastic bags and some people don't use bags or just put their purchases in boxes.

BENEFITS:

1. Knowing your purchase total before hitting the checkout - more info always good!
2. Feeling more appreciated that the store trusts you to pay for all items
3. Saving the time checkout would normally take
4. Feeling more free not having to deal with interacting with anyone
