It seems like scanning the items is a nice feature but not needed, especially if you need to go to one of these scanning stations to order your food. If there isn't a way to order directly from your phone regardless of location there should be. Perhaps a bit more then most online stores providing a more realistic way to purchase your food. When I read the title I interpreted as an online virtual store. A more basic view of the products with a searchable feature should also be an option. When you go shopping you most often buy the same things week in and week out (milk, bread, etc) it would be pretty awesome to set-up a rotating weekly schedule. If entire communities used this the cost of delivery would be offset by the costs of maintaining a physical store.
Did you notice the people happily saying that you could see the produce?
People don't trust some things without being able to see them, and food is one of them. Being able to recognise that a particular item is the one you like makes them happier.
Once they've used it a couple of times they'll be re-ordering without bothering with the scanning, but to bring in first-time buyers, this is very smart.
Another thing that I'm sure weighed in positively (at least subconciously) was seeing others do the same. On a singular device, the experience is very individual, could be experimental, and feels like shopping in a box: a tiny flat one, at that. Out in the public alongside others breeds a sense of community approval and helps reinforce the legitimacy of the method, especially as it is somewhat close to the original grocery shopping experience.
What a brilliant idea! The fact that you can see the product in full size as opposed to scale down to a phone or computer screen makes a lot of difference.
Outstanding idea and execution, they should have product booklets commuters can take away with them, simple magazine with smartcodes and shop at anytime.
Truly amazing. It never ceases to amaze me how people in orient Asia are eager to use technology in such an intelligent way. If this system were implemented here in my country (Spain) I'd bet (and I'd win) that the revenue would be insignificant and the vast majority of the ads would've been covered in graffiti in less than 1 month.
