What is NFC

What is NFC


The Near Field Communication (NFC) technology is a short-range (for up to four centimeters) contactless RF (radio frequency) communication standard. The technology allows a simple, rapid, intuitive and easily securable communication between two electronic devices. NFC relies on RFID technology (radio frequency identification) and has reached a high level of maturity.


The first two letters, “NF”, stand for “near field” and correspond to physical notions of propagation of electromagnetic fields. Thus, the “near-field” merely reflects a technical choice for two devices to communicate over very short distances, for security reasons, ease of implementation and low power consumption. This choice was made on RFID HF (High Frequency) 13.56 MHz technology that has been used for contactless smart cards and met an acceptable compromise to meet the functional and technical requirements.


By 2000, the introduction of the first integrated circuits specifically designed for contactless card readers (RFID HF) has led some experts to think of other possible applications then simple card & reader communication. Ideas rang out from all stakeholders, especially that to make communicate two readers together on short distances and bilaterally (detailed later as "peer to peer"). Then the proliferation of mobile phones and contactless payments and transportation cards led to thinking of smart card emulation or contactless RFID reader emulation functions.

Any questions please feel free to let us know.



Thus emerged the need to make coexist all these different needs, while capitalizing on the installed base of contactless readers and existing applications.
