Introduction to NFC
[attachment=39815]
Introduction
This document introduces the NFC technology in general and the specifics that are supported on Nokia devices.
This document is intended for developers who are new to NFC and are planning to develop applications for Nokia devices using the Qt/Symbian/Java APIs.
Introduction to NFC 5
What is NFC
NFC stands for Near Field Communication. It is a short-range radio technology that enables communication between devices that either touch or are momentarily held close together.
NFC is an open-platform technology, which is being standardized in the NFC Forum.
NFC is based on and extends on RFID. It operates on 13.56 MHz frequency.
NFC communication range is up to 10 cm. However, for best user experience with Nokia phones it is recommended that the devices are in touch with each other.
NFC standard supports different data transmission rates such as 106kbps, 212 kbps, and 424 kbps.
Reader
The reader is an active device, which generates radio signals to communicate with the tags. The reader powers the passive device in case of passive mode of communication.
Peer to Peer
In this mode, two NFC-enabled devices can exchange data. For example, you can share Bluetooth or Wi-Fi link set up parameters to initiate a Bluetooth or Wi-Fi link. You can also exchange data such as virtual business cards or digital photos. Peer-to-Peer mode is standardised on the ISO/IEC 18092 standard.
Note: The Symbian implementation for NFC currently supports initiation of Bluetooth link, while Wi-Fi is not supported yet. Also, the Java implementation for NFC does not support this mode of operation.
