Shadow QR Code Campaign Increases Sales 25%

Many retailers experience a slow part of the day which can be a difficult challenge to solve.  Sometimes the best answer is engaging your customers in new and creative ways.

South Korea’s largest retailer, E-mart, was seeing a a large dip in daily business from 12pm to 1pm and came up with a novel way to get customers into stores.  They created a shadow QR code that was only scannable between 12pm and 1pm when the sun was in a position to cast the correct shape shadow.  When people would see these shadow QR codes outdoors they could use their smartphone to read them.  Once scanned, they are lead to a ‘Sunny Sale’ homepage with special offers, coupons and a download for the Emart ecommerce app.  This simple yet clever campaign helped increase Emart’s sale by 25% during their once difficult lunchtime slump. The campaign was conceived and managed by Cheil Worldwide who were also responsible for the virtual grocery store in Hangangjin subway station in Seoul.
