In Seoul, retailer uses 3D QR codes and the sun to deliver discounts only during its quiet times

Korean Emart recently placed 3D QR code sculptures throughout the city of Seoul that could only be scanned between noon and 1 pm each day — consumers were given discounts at the store during those quiet shopping hours.

Periodic lulls in business are a fact of life for most retailers, and we’ve already seen solutions including daily deals that are valid only during those quiet times. Recently, however, we came across a concept that takes such efforts even further. Specifically, Korean Emart recently placed 3D QR code sculptures throughout the city of Seoul that could only be scanned between noon and 1 pm each day — consumers who succeeded were rewarded with discounts at the store during those quiet shopping hours. Dubbed “Sunny Sale,” Emart’s effort involved setting up a series of what it calls “shadow” QR codes that depend on peak sunlight for proper viewing and were scannable only between 12 and 1 pm each day. Successfully scanning a code took consumers to a dedicated home page with special offers including a coupon worth USD 12. Purchases could then be made via smartphone for delivery direct to the consumer’s door. The video below explains the campaign in more detail: As a result of its creative promotion, Emart reportedly saw membership increase by 58 percent in February over the previous month, they also observed a 25 percent increase in sales during lunch hours.
