Introduction tocommunication technologies. As a NFC is one of the latest wireless NFC short-range wireless connectivity technology. NFC offers safe — yet simple and intuitive — communication between electronic devices. Enables the exchange of data between devices over a distance of up to 20 centimetres. NFC-enabled devices only need to be ‘tapped together for them to connect via NFC
How NFC Works NFC is based on RFID technology that uses magnetic field induction to enable communication between electronic devices in close proximity. NFC operates at 13.56 MHz For two devices to communicate using NFC, one device must have an NFC reader/writer and one must have an NFC tag. The tag is essentially an integrated circuit containing data, connected to an antenna, that can read and written by the reader.
APPLICATIONSNFC application categories:Touch and Go: Applications such as access control or transport/event ticketing, where the user needs only to bring the device storing the ticket or access code close to the reader.Also, for simple data,capture applications, such as picking up an Internet URL from a smart label on a poster. .
Touch and ConfirmApplications suchas mobile paymentwhere the user hasto confirm theinteraction byentering a passwordor just accepting thetransaction
Touch and Connect: Linking two NFC-enabled devices to enablepeer to peer transfer of data such as downloading music,exchanging images or synchronizing address books
NFC and Mobile Payment
Adding NFC to Terminals Adds Value to MobilePayments
What is the Future? Nokia is active in the area of NFC since 2004 Together with Philips and Sony, founded the NFC Forum. Currently, global membership in the NFC Forum had exceeded 140 organizations.
The NFC Ecosystem is Broad
TECHNICAL BASIS AND FEATURES - It is intuitive (“touch and start”) - It is suitable for payment/financial applications - It interacts also with battery-less smart devices - It is low cost - Standardized in ISO/IEC 18092 NFCIP-1 (NFC Interface and Protocol - 1) - Based on RF-ID technology at 13.56 MHz - Operating distance typical 20 cm - Data rate today up to 424 kbps (up to 1 Mbps planned)
Low cost, NFC has very fast and easy configuration andpairing,Instant connection capability.“Out of the box”-No special software - No manual configuration and settings. - No search and pair procedure - User initiates the process - Simple data acquisition just by touching - Read data from any electrical device (interface dependent) - Read data from passive RFID tag
CONCLUSION In the near future NFC will be the frontrunner technology for data capture, data transfer and access control applications. NFC technology continues to evolve and develop new applications. It is going to bring revolution in mobile communications.
