This creative 'Emart' sunny sale campaign was created by a company called Esmart, which utilized the QR Code. Emart is a popular grocery store in Korea with 141 chains located within the country. The problem however, is that the company's sales tend to decrease drastically during the lunch hours.
In order to lure customers into the store, a giant shadow QR code was installed outside the store. It is activated with the sunlight, and only available between 12:00pm-1:00pm. Once the sunlight creates the 3D shadow, clients are then asked to scan the code which provides the customer with special sales and coupons, and also allows them to purchase items via the Emart app for home delivery.
This campaign helped draw the public's curiosity, so even people who weren't initially Emart shoppers decided to give it a try and the company saw a 58 percent increase in membership from the previous month.
