What is Near Field Communication (NFC)

what is nfc and how it works

NFC (Near Field Communication) as known as a short-range wireless technology, is a set of communication protocols that enable  simple and safe two-way interactions between electronic devices, to establish communication or perform contactless transactions by bringing them within a short distance (less than 10 cm) of each other. Normally, one of such devise is use to be a portable device like smart mobile phone.

NFC is rooted in radio-frequency identification technology (RFID) and operates at 13.56 MHz on ISO/IEC 18000-3 air interface.  NFC tags contain data are typically read-only, but some could be writable. They can be custom-encoded by their manufacturers or use NFC Forum specifications.

At 2004, Nokia, Philips And Sony Establish The Near Field Communication (NFC) Forum, which the NFC Forum defines five types of tags that provide different communication speeds and capabilities in terms of configurability, memory, security, data retention and write endurance.
