NFC unifies all contactless and wireless standards, thus enabling an unbelievably simple data transfer or for example a Wi-Fi connection establishment.
Near Field Communication (NFC) technology was developed in order to solve the wireless technologies dilemma, which enable even a substantially higher transfer speed but often for the price of a time consuming setup. It can be said, that NFC solves all cases – transfer of a small and even big amount of data. In the first case – at a transfer of small files or a small data amount, the NFC transfer speed is sufficient (up to 424 kbps) and in the second case – at a transfer of a big amount of data, the NFC enables to for example establish Wi-Fi connection in a moment, without a need for any manual setting.
NFC briefly:
- intelligent technology solving the wireless networks dilemma regarding an often laborious connection setup
- able to setup a Wi-Fi connection of a smartphone by a simple touch (approximation)
- also enables short range data transfer (max tens of cm)
- based on an RFID (ISO/IEC 14443 A&B and JIS-X 6319-4) – 13,56MHz
- hundreds of various possibilities of usage in an everyday life
NFC is based on an existing wireless communication standard – RFID (ISO/IEC 14443 A&B and JIS-X 6319-4). Ability of a duplex communication is ideal for an immediate data transfer or for establishment of connection via other wireless technologies by simplicity of a touch (approximation). For an end user it means a simple connection establishment, fast transactions and a comfortable data sharing. Similarly like RFID, even NFC devices exist as active and passive ones. Active devices are for example smartphones, pay terminals and other devices with their own power supply and a small antenna serving for data transfer, as well as for power supply of passive NFC devices, so called tags. Tags can have a miniature dimensions (similarly like at RFID) and they enable read, write but also an implementation of various applications.
NFC is suitable for example for:
– blue tooth connection establishment by a simple touch (approximation) of two Bluetooth devices
– connection to a Wi-Fi by a touch of a telephone to a router or to other NFC device (tag) containing access settings
– contactless payments
– intelligent access systems with a central access rights control
– data sharing and transfer (for example printing of a picture on a printer)
– wide possibilities in healthcare
– loyalty program
– transportation
– consumer electronics
– visit-cards, posters, where various information can be written in an NFC tag
