Detailed explanation-1: -What Is NFC (Near Field Communication)? Near Field Communication, commonly abbreviated as NFC, is defined as a wireless personal area network (PAN) technology that connects two compatible devices in very close proximity to each other, in order to enable slow but reliable data transfer.

Detailed explanation-2: -Near Field Communication (NFC) is a set of short-range wireless technologies, typically requiring a distance of 4cm or less to initiate a connection. NFC allows you to share small payloads of data between an NFC tag and an Android-powered device, or between two Android-powered devices. Tags can range in complexity.

Detailed explanation-3: -NFC is a special type of contactless technology in the IoT because: It communicates over a very short range (0-5 cm) for security. It is present in most iOS and Android mobile phones.

Detailed explanation-4: -NFC and Bluetooth are both relatively short-range communication technologies available on mobile phones. NFC operates at slower speeds than Bluetooth and has a much shorter range, but consumes far less power and doesn’t require pairing.
