Korea continues to set the standard in creative QR Code campaigns! In June last year Homeplus in South Korea had used QR Codes to create a virtual store in a subway station.
Now Emart, South Korea’s largest retailer has created shadow QR codes across the city that only become visible when the sun is at the correct angle in the sky i.e. between midday and 1pm. Consumers who scanned the QR Code during this period were re-directed to the Emart online store where they received $12 coupons for products that would be delivered to their homes.
The Sundial QR Codes were installed at 36 locations across Seoul and served more than 12,000 coupons. Emart membership increased by 58% and lunch hour sales went up by 25%.
