Edeka, a grocery retailer from Germany, found a a very creative way to get into the holiday spirit with the use of their in-counter scanners at their checkout lanes. Scanners all have the means to produce audio feedback for positive scans which, in many models, can be customized to specific pitches or sounds. Edeka put these programmable tones to use to make all their checkout lanes into a ‘playable’ instrument. Each lane plays a specific pitch so with a little practice their reps could perform Jingle Bells by simply scanning products in the right sequence.
