RFID technology brings revolution not only in functionality of tracking systems but in healthcare, libraries and field of manufacturing etc. also. Here I give you a brief description about RFID technology, hope it will be helpful for you.
Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
An RFID tag is a small object that can be attached to or incorporated into a
product, animal, or person.
RFID tags contain silicon chips and antennas to enable them to receive and respond to radio-frequency queries from an RFID transceiver. Passive tags require no internal power source, whereas active tags require a power source.
RFID is the abbreviated form of Radio Frequency Identification. RFID is akin to the bar codes but in RFID the electro magnetic coupling is used to transmit signals.
The main components of an RFID are silicon chips, an antenna and a transceiver that can be used anytime and anywhere.
The passive RFID tags require no power source while active ones with power backup.
