NFC is the abbreviation for Near Field Communication. It is a set of communication protocols that allows data to be transferred between devices only a few millimeters away (maximum of approximately 10 centimeters), usually in a back-to-back configuration.

NFC is one of the emerging technologies like RFID, BLE, Z-Wave, UHF, etc. With its ever-expanding boundaries, near-field communications has a wide range of uses beyond simplifying and speeding up the payment process. An enormous number of contactless cards and readers are used globally today. With a simple tap, NFC can also connect WiFi and Bluetooth devices across our homes.

NFC is based on RFID technology, although its transmission range is substantially shorter. NFC devices can store and transfer a variety of data kinds, and in comparison to RFID, it can store and send more data because they have more storage space. RFID devices can only carry simple ID information. As a result, it is more suited to situations where payment information, membership, and tickets are required.

There are various applications and implementations of NFC that are proving useful in numerous industries and have far-reaching implications. Some of the implementations are mobile payment; NFC is used by apps like Google Pay and Samsung Pay to enable contactless payments, in healthcare; it provides new possibilities for monitoring patients, home automation, Airlines; helps to reduce the on-boarding time, in hospitality/travel and leisure industry; can manage the access control system of the rooms and can also help with other functions such as booking the room and skipping the check-in procedure.
