NFC Explained: What is NFC? How NFC Works? Applications of NFC

In this video, what is NFC, How NFC works and some useful applications of NFC have been explained. And at the latter part of the video, NFC has been compared with the other technologies like Bluetooth, RFID and QR code. What is NFC? NFC stands for Near Field Communication. It is short distance wireless communication technology. So. when two NFC enabled devices are very close to each other (roughly around 4 cm), then they can communicate with each other using radio waves. How NFC Works? NFC enabled devices communicates with each other using radio waves. And three modes of communication is supported by NFC technology. 1) Card Emulation mode 2) Peer-to-Peer Mode 3) Reader/Writer Mode In peer-to-peer mode, both NFC enabled devices generates the radio wave alternatively and communicates with each other. In reader/writer mode, devices communicate each other using the principle of electromagnetic induction. The active device transmits the radio wave and the passive device responds ba
