When mid-day sales are
slumping, blame it on the sunny weather. Or, why not harness the power of the sun during
that lull to drive sales. Emart
did just that. They created a piece of art that uses the angle of the sun, much
like a sundial, to generate QR codes. Scanned QR
codes directed people to their online store where they could purchase time
sensitive “Sunny Sale” deals available only around noon when the shadows align
to make to code active. Impressive!
