What is NFC (Near Field Communication)

NFC technology

Near Field Communication (NFC) technology is a short-range wireless communication. NFC uses RFID communication protocols and data exchange formats. Using this, you can communicate with another NFC device or an un-powered NFC chip, called a “tag”.

This technology is being used in credit cards. The new credit cards are fitted with NFC chips which can be simply tapped against a NFC payment terminal to make payment. NFC is also used to make “smart posters” with embedded NFC chips. Tap your NFC enabled phone against them to get all the information you need about the poster.
