What is NFC (Near Field Communications)?
NFC or Near Field Communication, is a short range wireless evolved from RFID technology that makes use of electromagnetic radio fields instead of the typical direct radio transmissions used by technologies such as Bluetooth.
It is meant for applications where a physical touch, or close to it, is required in order to maintain security. NFC is planned for use in mobile devices for marketing, payment, in conjunction with an electronic wallet, and for setting up connections between
NFC creates a new and universal interface to existing devices through simple touch interaction.
All NFC transactions take place within a very small area, from a touch to 4 centimeters.
NFC is able to replace the pairing of Bluetooth-enabled devices, or the configuration of a Wi-Fi network through PINs and keys, by simply touching the two devices to be paired or connected to the network, or by touching the device to a tag.
