Passing by or shopping in the metro ?

South Koréa

Because people in South Korea are working long hours and they often don't have time to go shopping, grocery chain Tesco came up with a brilliant idea and an effective way to sell their products. The Korean subsidiary Home Plus put up billboards in subway stations with their range of products, accompanied by QR, or Quick Response codes. All people had to do now is scan the QR codes with their cell phone and the groceries were delivered to their doorsteps.
