GameStop, the Texas-based international games retailer which has taken a pioneering interest in many innovative in-store technologies, has been working with specialist firm Shelfbucks to install beacons in test stores. Seven to ten devices are now present in each of 150 stores – a big increase since the rollout began with just 35 locations last year – to give shoppers product information relevant to nearby displays, inform them about the availability of loyalty points, and provide information on individual shoppers’ loyalty profile to staff via their iPads.
