■ 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.
