Quick Intro to NFC

Quick Intro to NFC

As I’ve recently added blog posts on Mobile Payments, Apple Pay, Android Pay and Samsung Pay – all which use NFC – I thought I’d add a post for NFC itself.

What is NFC?

Firstly, NFC is Near Field Communication – a technology more catchily known as NFC.

Here’s the Wikipedia techie info “NFC employs electromagnetic induction between two loop antennae when NFC devices – for example a ‘smart phone’ and a ‘smart poster’ – to exchange information, operating within the globally available unlicensed radio frequency ISM band of 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s.”

In the real world, that means NFC is technology used in ‘Tap and go’ or ‘Proximity card’ services – including Apple Pay, Android Pay and Samsung Pay, plus many other services.

NFC is a method of wireless data transfer between two enabled devices that are in close proximity (about 10 cms) An NFC-enabled device will detect another NFC-enabled device and data can then be transferred between the two devices.

NFC is a power-efficient technology, as it uses chips which run on very low amounts of power.

Uses for NFC

  • Mobile Payments, used in Apple Pay, Android Pay, Samsung Pay
  • Used in Android Beam and S-Beam technologies – where it bootstraps a more capable connection, such as Bluetooth and/or wifi
  • Microsoft’s Windows Phone will enable Microsoft Payments in Windows 10, using NFC
  • Sharing contacts, files etc between devices
  • Potential for electronic identity and access
  • Can be used with NFC tags or stickers, to automate tasks on mobile devices
  • Used in some video games
