Understanding Near Field Communication (NFC) Technology and Its Applications
Near Field Communication (NFC) is a short-range wireless communication technology that enables data exchange between devices when they are brought close together, typically within a few centimeters. Operating on the principles of radio frequency identification (RFID), NFC allows two-way communication, enabling both devices to send and receive information. This technology has become a key enabler of modern contactless interactions, offering convenience, speed, and enhanced security across various applications.
How NFC WorksNFC operates at a frequency of 13.56 MHz and enables data transmission at rates up to 424 kbps. It functions in three modes:
Reader/Writer Mode: A device reads data from or writes data to an NFC tag embedded in posters, cards, or other objects.
Peer-to-Peer Mode: Two NFC-enabled devices exchange data directly, such as contacts, photos, or files.
