A lovely execution of a famililar idea.
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.
The video below explains all this in more detail in a frankly, pretty chee-zee way, pity.
