It sounds a bit confusing from the article. I I'd like to hear more about how it's going to work. So a shop is closed, you can order from the window, and a courier will deliver it within the hour. But if the shop is closed, where is the courier getting the goods from? A warehouse? That means this only applies to major retailers and not the smaller ones.
Also, if you're out and about you really don't want a courier appearing at your doorstep within an hour. They'd also need to give you flexibility to pick the time when your product is delivered.
Can't they install these devices at certain places where people gather, like near a bus stop, and let them display goods from various shops instead of just the one shop?
