RFID—What is it?
Overview
RFID (Radio Frequency Identification) is a means of storing and retrieving data through
electromagnetic transmission to an RF compatible integrated circuit, and is now being seen as a
radical means of enhancing data handling processes.
A range of devices and associated systems are available to satisfy an even broader range of
applications. Despite this diversity, the principles upon which they are based are quite straight
forward, even though the technology and technicalities concerning the way in which they operate
can be quite sophisticated.
Physics and Electronic Foundations
System Components
RFID systems have several basic components or technical characteristics that define them.
These are:
• A reader, including an antenna
The device that is used to read and/or write data to RFID tags.
• A tag
A device that transmits to a reader the data.
• The communication between them
RFID uses a defined radio frequency and protocol to transmit and receive data from tags.
Types of RFID Tags
RFID tags can be segregated into two major classifications by their power source:
• Active tags
Active tags contain both a radio transceiver and battery to power the transceiver.
Because there is an onboard radio on the tag, active tags have substantially more range
(~300 feet) than passive or “active/passive tags.” Active tags are also considerably more
expensive than passive tags and, as with any battery-powered product, the batteries
must be replaced periodically.
• Passive tags
Passive tags can be either battery or non-battery operated, as determined by the
intended application. Passive tags reflect the RF signal transmitted to them from a reader
or transceiver and add information by modulating the reflected signal. A passive tag does
not use a...
