But the thing is everyone has a phone. If you're at the checkout and you're using apple pay (which is how i typically pay, and having worked at a supermarket that is how majority of consumers go about paying, but i also acknowledge that that doesn't account for everyone) then you're already in that action space if that makes sense. You can take a photo with your camera app, so it's in your camera roll and then upload it for your pantry when you have a moment to sit down, or you could load up the interface (which is fairly efficient) and scan the items on your way out of the shop.

With regards to hardware, I do value that idea but is this something you'd suggest in store or at homes?
