Radio frequency identification or RFID is a broad-based technology that impacts business and society. With the rapid expansion of the use of this technology in everything from consumer purchases with the use of Touch Screen Monitors and credit cards to security Card Personalisation tags for companies, universities libraries and hospitals. To tracking birds of migration and other endangered creatures over simpler things like parking in a car park where you have to slide a card that is already using RFID Technology. RFID Components, readers and tags are used extensively today and yet others still do not know the benefits brought by this kind of innovation or even how RFID Technology works.

RFID is radio-frequency identification; the main purpose of RFID’s is on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader. Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal.
