The South Korean Tesco variant, Home Plus, is enjoying a boom in popularity after successful implementation of its online-based QR powered shopping experience.
Paying attention to the fact that Koreans work 2,256 hours each year (over 100 hours longer than the next longest-working country), or a 44 hour working week, Home Plus decided that people didn't have enough time to visit the supermarket.
So, in order to give shoppers that supermarket feel whilst still allowing them to shop online, this brilliant subway-based QR code system was put in place.
And it seems to have paid dividends as Home Plus is now the number one online grocery shopping portal in South Korea, and has seen a 130 per cent increase.
We just hope Boris is paying attention - we'd love to see a similar system on the Tube.
