Korea is one of the busiestcountries in the world with one of the hardest working populations this obviously leads to the old problems of free time once Tesco did some research and found one of the most loathed things for koreans is the weekly food shop as this takes up more of their spare time.
So Tesco designed something where necessity meets design a virtual store but on advertising boards in trains stations see the video bellow for more details.
As online shopping becomes more popular the world over is this a way to help customers save time and to make your brand more widely noticed at the same time both advertising and selling at the same time all that happens I that you scan the qr code of the product you want with your smart phone then this updates the app on your phone with those products then those items are delivered to your door a great way to kill time while stuck waiting for a buss or a train on your way home or on your comute to work.
