Here is a very smart use of QR codes from Korea, a region known for it’s high levels of traction with this technology. This campaign from Emart, one of the largest retailers in Korea, needed to increase sales during lunchtime.
Emart introduced “The Sunny Sale” which involved a three-dimensional QR code that was placed across the city and could only be scanned during the hours of 12 and 1 each day, due to the sunlight casting a shadow to complete the QR code. Anybody who did scan the code was given a special discount code with 25% off that could be redeemed in store or through their mobile e commerce site. Emart have seen a great increase in sales during the lunchtime period and have doubled the number of locations for this promotion. This is a very smart way to effectively use technology to drive sales.
