I think you can achive that way easier, than with a box for every item. You could Show an example item, and when you pay for it, it could be prepared for you with all the other items at the Exit.
But I don't think, this is really a good use of BTC. Do you really want to pay for every item individually? Sounds like a lot of work even if it just scanning and pressing "send".
When I think, about it, there could be this box at the Exit, which can be unlocked by paying for it.
This wouldn't be a good idea either. If you're just picking up one of those "example items", then at the end someone else has to go around the store or the backroom storage to hunt down all your items. This is a lot of service required. Imagine the cost of hiring an army of employees to run around to gather items for the customer.
I was more thinking about some Kind of full-automatic System, not about People running around in the storeroom collecting your things.
And you are not
picking up example items, you just scan them, so they get prepared.
Fully automated? Do you have any idea the cost and infrastructure required to implement this idea? If this was easy and cheap, then we'd be seeing all these automated machines replace all the employees in groceries and other B&M stores by now.
I never said, it is easy and cheap, but it would be profitable over time.
The question is not, if somebody could implement it, I am sure, we are technology capable of doing that.
The question is, if people would go there shopping.
