You may not know what radio-frequency identification or RFID is but you may have already seen one if you have purchased a CD and DVD with anti-theft tag on its case; if you live in the Northeastern US and use the E-ZPass system to pay tolls or if you have obtained a US passport since October of 2006. As RFID's are adopted for more uses in our worlds, we want to share some background on this technology. RFID is defined by Wikipedia as:
a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from several meters away and beyond the line of sight of the reader. The application of bulk reading enables an almost-parallel reading of tags.
The tag's information is stored electronically. The RFID tag includes a small RF transmitter and receiver. An RFID reader transmits an encoded radio signal to interrogate the tag. The tag receives the message and responds with its identification information. Many RFID tags do not use a battery. Instead, the tag uses the radio energy transmitted by the reader as its energy source. The RFID system design includes a method of discriminating several tags that might be within the range of the RFID reader.
