By 2020 retail virtual avatars – on screens and in holographic projection – will start to become popular. Their A.I. will be powered by realtime analysis of affinity data for product recommendations and neural network enhanced sales closing strategies. Similarly, service desks in hotels, shops, banks and other retail destinations will disappear. They will be replaced by nomadic staff equipped with in-ear devices that provide them real-time insights into your preferences, based on your NFC emissions.
