The RAIN in Smartphones workgroups are focused on driving RAIN reader integration into smartphones. This integration will enable enterprises and people to engage with everyday items, in the supply chain, in stores, and in everyday life, and open the door to new use cases and revenue streams, from consumer engagement to seamless omnichannel shopping, to end-of-life recycling.
