According to home plus (also known as Tesco), the Koreans are the second hardest working people in the world. I don't know who is the first, but according to my source, the Koreans think shopping is a real chore in their schedules.
Home plus has shopping easier by virtual grocery store made course in u-Bahn-Stationen. While u-Bahn drivers wait for the next turn, they can go through the pictures of food look like grocery store aisles to the.
The only difference is that images of food have QR codes. A Smartphone user takes image of the product, and then pay for the items. I suspect that the payment is done through some online services. I know for sure that the actual items are delivered at home.
This has made them the second-largest online-shopping company in Korea according to HomePlus. Food are people like the service, and there they wait as soon as they come home.
There is no reason why this can be in terminals, u-Bahn in New York City? Perhaps they are already, as it seems an obvious target group for this service as follows. Me I question, if there is a fee for service or the food only costly is? Someone has to pay for these service
