Introduction to NFC
- NFC is one of the latest wireless communication technologies. As a 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 10 centimeters .
- NFC-enabled devices can simply point or touch, making application and data usage easy and convenient.
- The design includes a near-field transmitter and receiver to send data from one device to another
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 (initiator/target) 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 be read and written by the reader.
- Maximum transfer bit rate of 800kbps.
- No special software is required.
