Instead of the typical bar stamp, they replaced it with a QR code. When the QR code was scanned from 8pm – 10pm, patrons received bar offers and discounts on some of their favorite drinks. From 10pm to 6am, the QR code scan provided local cab service numbers. From 6am to 4pm, the QR code scan provided hangover tips.
It’s a somewhat interesting concept that utilizes the same QR code for several different interactions.
Over 85% of bar patrons with smartphones used the Buddy Stamp in the club and shared their evening on Facebook."
