It is basically a way for your smartphone or watch to communicate with something that is close by. NFC generally works with a radius of about 4cm by using a wireless connection between the devices. This method is perfect for two-way communication with both the involved devices being able to send and receive data. One thing to note here is that the NFC connection does not depend on 3G, LTE, or Wi-Fi. The best part about it is that it doesn’t cost anything!

How does NFC work?

To put it simply, Near Field Communication basically uses wireless data transfer to detect a device in close proximity to communicate with it without requiring an internet connection. It is fast and reliable. You don’t have to authenticate anything and once you have your digital wallet set up, the process is pretty automatic. The RFID tech used helps the NFC chip with one part of the wireless link. Once this is activated by another chip, the two devices can start communicating data when they are close to each other.
