NFC & RFID

Near field communication or NFC is a wireless communication technique which is shared between two devices, NFC chip or device and NFC reader. For NFC to work optimally, the two devices should be placed near each other, and the distance is usually defined to be not more than a few centimeters. Presently, NFC technology is mainly used for making payments. This payment system is initiated and facilitated by the NFC chip installed in smartphones and the NFC code reader. The robust NFC technology can act as your credit card for making payments, a keycard, and also an ID card.

RFID or radio frequency identification is one type of communication channel. Near field communication is an extension of RFID. RFID technology is very popular in the field of tagging. RFID works on radio frequency, which is either active or passive or sometimes a mixture of both. The frequency upon which near field communications technology works is a totally passive one. Let’s have a look at the differences between the two technologies.

  1. NFC is an extension of RFID.
  2. RFID works at a longer distance range whereas NFC’s transmission capability is restricted to few centimeters.
  3. Near field communication technology is mainly applied for security purpose whereas RFID has a great variety of applications.
  4. NFC can be installed in the latest smartphones but RFID cannot be installed in phones.
