What is NFC? Everything you need to know

Have you ever wondered what makes tap-and-go services like Apple Pay, Android Pay and Amiibo work? As much as it seems like pure magic, it isn't. Simply put, it's a method of wireless data transfer called NFC (Near field communication) that detects and then enables technology in close proximity to communicate without the need for an internet connection. It's easy, fast and works automagically The tech involved is deceptively simple: evolved from radio frequency identification (RFID) tech, an NFC chip operates as one part of a wireless link. Once it's activated by another chip, small amounts of data between the two devices can be transferred when held a few centimeters from each other.
