RFID (Radio Frequency Identification)

RFID has become very popular now a days, it being used as auto data collection (ADC) technology in many fiel
ds for example Passports, Libraries, School, Universities, Hospitals, Stores and Museums.

RFID is way of tracking objects using the radio waves typically called an RFID tag. Some tags can be read from several meters away and beyond the line of sight of the reader.

There are two major parts, One is an integrated circuit for storing and processing information, modulating and demodulating aradio-frequency (RF) signal, and other specialized functions.The second is an antenna for receiving and transmitting the signal.

On the other hand some say that using this technology for identification is a security threat, for example countries that put RFID in passports include Norway, Japan, most EU countries including Ireland and UK, Australia and the United States, Serbia, Republic of Korea.
