Abstract

NFC (Near Field Communication) is a very popular wireless communication protocol based on electromagnetic induction. NFC is built into many electronic devices, including most smartphones. It is utilized in many applications, such as Apple Pay and Android Pay. However, NFC suffers from major limitations including low range and strict alignment requirements, to the point where devices’ NFC ports nearly touch when communicating. Additionally, NFC emits large amounts of RF (radio-frequency) radiation, making it unsuitable for certain EMI (electromagnetic interference) sensitive environments. Our Li-Fi++ product is a wireless, optical communication system that can function similarly to NFC and overcome the stated limitations.
