Koreans visit supermarket through subway billboards.

Tesco has launched ‘virtual supermarkets’ at subway stations in the South Korean capital of Soul.

Research revealed that Koreans had little time for grocery shopping and so the supermarket giant has created billboards of products with QR codes attached to the picture of each product. Shoppers scan their order using an app on their smartphone and organise delivery.

Tesco says that its local subsidiary, HomePlus, has now become the leading online supermarket retailer in Korea and has bridged the gap between its leading offline rival.
