Will the NFC unify all wireless technologies?

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:
- bluetooth connection establishment by a simple touch (approximation) of two Bluetooth devices
- connection to a WiFi 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
