Tesco which is apparently also known as Home Plus in South Korea have found a new way to attract customers, simply by putting billboards and posters with QR codes at the local subway stations, so people can look for the items that they need while they are waiting for their train.

Shopping this way is simple, just scan the QR code with your smartphone, and those items will be added to your virtual shopping cart. We still aren't sure how the payment system works, but we know that products arrive your home address shortly after you've reached your home via delivery, so you won't have to make unplanned visits to the grocery on your way home ever again.

This idea works amazingly well in South Korea, I wonder when this technology might arrive Great Britain?
