■ What are RFID and NFC?
RFID
RFID technologies use radio waves to automatically identify individual objects. By emitting a short-range radio
signal, the RFID reader device supplies power to an otherwise inactive RFID tag, allowing the device to read the
tag or write data to the tag's memory.
The RFID reader is a short-range device (reading range 0-5 cm) and it converts the radio waves returned from
the RFID tag into a format that can then be passed on to an application in the phone.
To transmit data from the RFID tag to the RFID reader, Nokia Field Force NFC shell uses the radio frequency
13.56 MHz, which is the most widely used globally available frequency for RFID.
NFC
NFC (Near Field Communication) is a short-range radio frequency technology that evolved from a combination
of contactless RFID and interconnection technologies. The NFC device allows users to read small amounts of
data from tags, as well as to communicate with other devices, by a simple touch.
