Bluetooth proximity marketing allows marketers to send messages like text, audio, and interactive apps to Bluetooth devices within a 100m radius. This allows marketers to upload offers and discounts to local devices at stores and malls. Visitors then receive pop-ups on their devices with the offers which they can accept, view, and potentially use to make a purchase. Bluetooth interaction is seen as a low-cost and non-intrusive way to potentially boost sales compared to traditional print advertising.
