WHAT IS:-(N.F.C) !............. Near Field Communication (NFC) is a set of communication protocols that allow two electronic devices to communicate over a distance of 4 cm (112 inches) or less. NFC provides low-speed connectivity through a simple setup that can be used to bootstrap higher-performance wireless connections. Like other "proximity card" technologies, NFC is based on inductive coupling between two so-called antennas present in NFC-enabled devices (such as smartphones and printers) rotating in one or both directions at a frequency of 13.56 MHz. . A globally available, unlicensed radio frequency ISM band using the ISO/IEC 18000-3 air interface standard with data rates from 106 to 424 kbit/s. The standard was provided by the NFC Forum. This forum was responsible for promoting technology, setting standards, and certifying device compliance. If it meets the criteria to be considered a personal area network, it can be used for secure communication by applying encryp...
