Uniqlo stores around me almost have this implemented. You don't scan the individual items, you just place your basket on the machine and it somehow knows every item in there. Super fast and convenient. I think it's only a matter of time.
It scared the hell out of me the first time because it somehow knew what I had in my arms and I didn't know what to scan to check out. But the items kept appearing and I didn't know if they were actually mine or not and it was a very creepy black mirror-esque experience for me.
I was just at the grocery store tonight and saw a new shopping cart, I thought it was a touchscreen to serve up ads and thought fuck that why the fuck would anyone want that, decided to go take a look at them and it’s kinda the same idea as the vid, a clunkier version of course
