Pretty much the title. Like, get those handheld scanners and attach them to the carts. I scan items as I put them in, roll up to a “register” where the cart is weighed and verified by a cashier. I just hand over the cash then leave. Or even better, install load sensors in the cart.
Usually I like to pack my groceries into my boxes as I get them into the cart. Keeps things orderly and neat and I also don’t buy more than I can carry home. But this means I have to unpack them to place on the belt then pack them all over again after paying. It would be kinda nice to just pay by the cart load.
The grocery store I often go to had these barcode scanners you could borrow at the entrance and scan your stuff as you go, along with scales on which you could print a barcode sticker for the stuff you pay by weight.
Once you were done, you’d scan a QR card at the self-service checkout to upload all the stuff you scanned, then pay.
It was awesome, you could just pack as you go. Unfortunately they scrapped the project once they found out that the amount of theft was significantly higher with this system. So yeah, we can’t have nice things 😒
