Near FieldCommunication (NFC)
- What Is NFC ?
- NFC or Near Field Communication is a short range frequency wireless communication technology.
- NFC is mainly aimed for mobile or handheld devices.
- A radio communication is established by touching the two phones or keeping them in a proximity of a fewcentimeters (up to 10 cm) .
- It allows for simplified transactions, data exchange, and wireless connections between two NFC trade mark devices.
- Allows communication between
- Two powered (active) devices
- Powered and non self-powered (passive) devices.
2. How does it work ?
NFC is based on Radio Frequency identification (RFID) technology
The technologo works via magnetic field induction technology and operates on an inlicensed radio frequency band.
3. Specification and Importance
It operates within the globally available and unlicensed radio frequencyband of 13.56 MHz, with a bandwidth of 14 kHz.
Distance of 10 cm or less
Supported data rates: 106 Kbit/s to 424 Kbit/s For two devices to communicate using NFC, one device must have an NFCreader/writer and one must have an NFC tag
4. Application of NFC
Also with future prospects and news about NFC as
Vehicle Ignition : A NFC enabled vehicle can be unlocked and started just by tapping the user’s NFC device onto the vehicle removing the need of carrying a pair of keys. It can even be used to communicate between the device and the vehicle and monitor the vehicle’s health through some specific app
Unlock Door : Smart keyless doors can be made by implementing NFC technology onto doors, where a single tap of the device onto the door would unlock it eradicating the pain of inserting the key and unlocking it.
Google is working with Citigroup and MasterCard on NFC mobile payment solution
Airlines move closer to NFC tech for passengers- NFC allows a Smartphone to be used to “tap and check-in” or “tap and board” their flight
Nintendos Wii successor, the Wii U, will come equipped with near-field communication (NFC) technology
Nokia went on record to say that all future Symbian devices will have built-in NFC support, a de-facto feature• Recently “Ra.One” became the first Indian movie to be marketed through NFC
5. NFC and others wireless technologies
NFC is complementary with existing wireless standards. It can be used to initiate WLAN, Bluetooth and other wireless connections without going through configuration menus. These connections are established simply by holding the two NFC products close together, or by configuring a device with contactless smart media.
