RFID stands for Radio-frequency identification. RFID Technology uses an electromagnetic fields to automatically identify and tracking tags attached to any vehicle or objects. RFID tags contain electronically stored information. There are three types of RFID tags such that Active Tag, Passive Tag and Semi-Passive Tag. An RFID system consist of three components: Antenna, transceiver and transponder.
The RFID component on the tags be contained in two parts: a microchip that stores, processes and deal with the information and an antenna to receive and transmit a signal. To interprets the information encoded on a tag, a 2-way radio transmitter-receiver called a reader transmits a signal to the tag using an antenna. The tag responds the information written in the memory bank. The reader will emit the read results to an RFID computer program.
RFID Tags
Active Tag: Active tags has its own battery that is used for broadcasting signals over great distances. Generally, it is bigger in size and suited of carrying more information.
Passive Tag: No internet power source. The power to tag is acquired by electromagnetic field generated by signals of RFID reader. It is much cheaper.
Semi- Passive Tag: It is fixed with an on-board battery that drives the chip’s circuitry but power for communication of the signal is derived from the reader’s electromagnetic field as in the case of passive tags.
RFID Reader
A radio frequency identification reader (RFID reader) is a device used to gather information from an RFID tag, which is used to track individual objects. Radio waves are used to transfer data from the tag to a reader.
Working of RFID
RFID belongs to a class of technologies referred to as Automatic Identification and Data Capture (AIDC). AIDC technique works automatically identifying objects, collect data about them, and enter those data directly into computer systems with no human interruption. RFID methods uses radio waves to complete this. At a basic level, RFID systems includes three components: an RFID tag or smart label, an RFID reader, and an antenna. RFID tags consist of integrated circuit and an antenna, which are used to transmit data to the RFID reader. The reader then converts the radio waves to a more utilizable form of data. Information gathered from the tags is then transmitted via a communications interface to a host computer system, where the data can be stored in a database and analyzed at a later time.
