RFID TECHNOLOGY

RFID Stands for Radio-Frequency IDentification. It refers to small electronic devices that consist of a small chip and an antenna. The chip typically is capable of carrying 2,000 bytes of data or less.
RFID technology is a wireless technology that allows for automated data collection and a unique identification of objects.
RFID systems are composed of RFID tags attached to the objects, readers that can read the tags from a distance, and application software.
The reader has two parts – a transceiver and an antenna.
The transceiver generates a weak radio signal that may have a range from a few feet to a few yards.
The signal is necessary to wake or activate the tag and is transmitted through the antenna.
The signal itself is a form of energy that can be used to power the tag.
Every RFID enabled object has its own unique identification number (ID).

Tags can be classified into three main groups based on power supply namely, passive, semi-passive and active.
RFID systems consists of an antenna and a transceiver, which read the radio frequency and transfer the information to a processing device, and a transponder, or tag, which is an integrated circuit containing the RF circuitry and information to be transmitted.
