Homeplus turned subway walls into virtual shelves, shoppers scanned QR codes while waiting

In 2011 Homeplus (Tesco's Korean venture) was stuck at #2 behind E-mart, and the gap was store count — a race that could only be bought with real estate. Meanwhile Koreans worked some of the longest hours in the OECD and dreaded the weekly shop; smartphone penetration was exploding.

Cheil Worldwide's Seoul office papered subway platform screen doors with life-size photographs of supermarket shelves, laid out exactly like the real aisles. Commuters scanned QR codes into a cart while waiting for the train; groceries arrived home the same evening. The store had come to the dead time.

Life-size shelf photographs went up in subway stations; commuters scanned QR codes while waiting and groceries arrived home the same day. The store came to the dead time.

Turned subway platforms into virtual stores: life-size shelf photos with QR codes let commuters shop while waiting, and same-day delivery closed the loop.

Subway platforms are a captive, idle audience with phones in hand.

Life-size shelf photos mimic the store layout, making browsing intuitive.

QR codes let commuters shop without leaving the platform.

Same-day delivery closes the loop, so no physical store is needed.
