NFC, Near Field Communication & It’s Possibilities

NFC, Near Field Communication:

How does NFC work?

NFC works similarly to Bluetooth technology, allowing two devices to interact with each other. However, NFC works only in very close proximity – theoretically up to 20cm (7.9in), but the optimal operating distance is generally around 4cm (1.6in) or less.

  • NFC technology is based on radio-frequency identification (RFID), which allows a mobile device to send radio waves to another device or RFID-enabled tag and trigger a certain action.
  • The main advantages that NFC has over other wireless communication technologies are energy efficiency and relative security from third-party attacks because of the short-range data transmission. It is virtually impossible for a hacker to get in between your mobile device and the other NFC enabled device owing to the close proximity of 4cm or less between the two.
  • NFC also uses less power than, for example Bluetooth, which is convenient when it comes to making mobile payments or other activities. It will instantly pair with the other NFC enabled device or tag while only using a fraction of the power of a Bluetooth device.
  • NFC also operates on a much lower frequency (13.56MHz) than Bluetooth (2.4-2.5GHz).
  • As a standards-based connectivity technology, NFC integrates various contactless technologies, which allows for solutions in the following areas:
  • Customer loyalty programmes
  • Mobile Payments
  • Access control
  • Healthcare
  • Public transport
  • Data collection and exchange
  • Time and attendance
