Near Field Communication

Near Field Communication or NFC is the next generation short-range high frequency wireless communication technology which enables the exchange of data between devices build with this technology. Mobile handsets are the main targeted devices for this technology. Services built on top of NFC enabled mobile handsets enable users to share and receive information instantly, interact with other NFC enabled devices, and even make fast and secure mobile payments.

The technology is built up on the existing RFID standards. However, there are minor differences, and NFC devices cannot interact with some of the legacy systems. Near filed Communication devices are operating at at 13.56 MHz and can transfer data at up to 424 Kbits/second. Communication between two NFC enabled handsets is started and completed with a simple proximity wave or touch of the two devices to each other The communication can also imply passive parts also in the form of an NFC tag. These tags gains power for the communication from the RF fields emitted by an active NFC device.

The real power of NFC relies in combining with contactless smart card infrastructure. The mobile handset user can make transactions just by touching his phone to a NFC credit card reader or ticket gate. Payment information, such as credit cards, loyalty cards, or your travel ticket are securely stored in the integrated smart card chip inside your phone. NFC technology enables all these legacy applications to be used on an mobile phone, providing more convenient , fast , and secure way of shopping or travelling.

When using an NFC enabled phone with a NFC tag the phone can read small amounts of data from the RFID service shortcut tags, so for example the service shortcut contained inside the tag is launched just with a simple touch or tap.
