At WWDC 2017, Apple announced a long wanted system framework for developers, CoreNFC. If you are not familiar with NFC, simply put, NFC (short for Near Field Communication) allows two devices to communicate with each other when placed within 4cm of each other. Most businesses put NFC chips in cards, enforcing tighter security of who can enter a building. Apple’s CoreNFC currently supports one single NFC format, NFC Data Exchange Format, or NDEF (commonly used in most tablets and phones on the market today).
