Near Field Communication (NFC)
NFC - Near Field Communication is a great way to engage with your customers. NFC is a wireless communication technology (a little like WIFI or Bluetooth). It allows transfer of data between two devices, such as a mobile phone and NFC tag. Typically NFC is used to pass data from one device to another. So you might use NFC to pass data from an NFC enabled mobile phone to another NFC enabled mobile phone, from a mobile phone to a payment terminal, or from an NFC tag to a mobile phone.
NFC technology works only at close distances - typically around a few centimetres. This close range makes NFC perfect for interaction and means that tags can't 'accidentally' be read or used for unwanted tracking. The 'tap' action is therefore quite specific and part of the appeal of NFC as opposed to other longer range RFID technologies.
Almost all new smartphones now have NFC built in. In fact, nine out of ten of the top mobile manufacturers have now adopted NFC.
