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.
Yeah, seen something like this in the UK. You take a scanner and scan everything as you shop, then just lay the bill as you exit. To begin with they even offered a discount I think. But they didn’t have a weigh option, just that they’d check some carts ‘at random’. My understanding was, like self checkouts, even if there’s a little more theft it’s more than made up for by less workers.
