The alternative shopping experience lets commuters on a South Korean subway use their smartphone to grab a range of everyday groceries. A wall in a subway station was decorated with a range of images, all showing food, drink, and other daily essentials; all "shoppers" (if you want to call them that) had to do was scan a QR code of a desired product, and it was instantly added to their virtual shopping basket, ready for home delivery.

As the above video shows, Tesco sees its move into the "virtual" shopping space as a way for the company to get more customers without having to build more brick and mortar stores.

It's a clever and very visually engaging idea, and one things for sure: all those travelling on the subway will have time to kill whilst waiting for their train, so why not get the weekly grocery shopping done while you're waiting? The only down side to this: It's a very hands-off way to get your grocery shopping done; I like to see and get a feel for what I'm buying.

Would you get your grocery shopping with just your smartphone?
