What is NFC (Near Field Communication)


A technology is a modern starch, and works on electronic devices, and allows them to communicate between them; through the contact between them, or enter within the field of association available to each device to communicate the other; As it allows you to use this technology in many commercial areas such as: commercials while shopping in malls; the device that supports this property can be rounded up and read its data and information including: product name, origin, date Production, and history only Price, discounts and other things. It can also be used at airports for flight schedules, incoming and outgoing aircraft, and for any other services.


 History of the NFC


 The history of the NFC technology dates back to 2002; the technology was developed in collaboration with Philips and Sony with Nokia; based on the technology of telecommunications; research and development since mid-century In the past, RFID technology, which allows for the determination of a particular frequency of a particular radio wave, has been used to determine the identity of the device from which such radio waves are produced, using software that allows it. 

NFC Working Principle


 The NFC technique operates at a frequency of 13.56 MHz, which is generated in magnetic induction based on the magnetic resonance phenomenon, where an inductive pairing is generated by approximating a pair of loop antennas from each other; Each in the magnetic induction circuit; this results in a double resonance; its waveguides are used to transmit data through a signal signal carrier; by including each other; through the so-called modulation process. 

Types of NFCs 


NFC devices differ in the way they provide the power needed to operate, so that one of the devices (transmitter or receiver) is idle (not powered by the power needed to operate itself) or, conversely, effective, The transmitter is idle, its electrical circuitry is equipped with the energy needed to exchange data, through radio waves transmitted by the receiver, or vice versa.
