Peer to peer (or point to point) as explained below. There are three modes in which NFC tag and reader works viz. NFC Network Modes-Card Emulation, Reader/Writer, Point to Point(Peer) Here Initiator polls the other devices which comes closer to it and the other NFC device referred as target Transmits only when no other signal is there on channel. Here one of the two NFC devices will function as initiator which first listen on channel and This is also referred as "Listen before Talk". One NFC device transmits while other device receives. In active-passive mode, passive device derive its power from received EM waves of the active device.īasic mode of communication is half duplex in NFC, where in In active-active mode, both the NFC devices will have their own power while These devices operate either in active-active or active-passive modes. NFC tag can be active as well as passive device. Let us understand how NFC works as part of this NFC tutorial.Īs mentioned NFC network consists of two devices known as initiator device and target device. Refer features of NFC-A, NFC-B, NFC-F types➤. There are three types of NFC forum specifications viz. Table:1 NFC network features or NFC capability NRZ-L, Manchester, Modified Miller, Read More➤ Automatic running of scheduled features in the NFC phone.įollowing table summarizes features of wireless NFC (Near Field Communication) technology.Ĭard Emulation, Reader/Writer, Point to Point(active & passive).Banking payments using NFC compliant credit card to enhance security.Verification of authenticated person having NFC ID card.This technology allows two devices housing NFC chip to communicate for various applications for example, It is a contactless mode of communication using electromagnetic waves. It is a short range low data rate wireless communication technology operating at 13.56 MHz frequency. How NFC works, NFC protocol stack and NFC test equipments.Īs mentioned NFC is the short form of Near Field Communication. This tutorial on NFC protocol also describes NFC frame, NFC modes, This NFC Tutorial covers Near Field Communication System basics. NFC Tutorial | Tutorial on NFC Protocol | How NFC works
