What is Radio Frequency Identification (RFID) & Wireless RF Sensors? – See more at:

The RFID Network website has a comprehensive overview of RFID basics online at: as well as Guides, information on suppliers and many “How to” videos online.

According to an extensive article on Wikipedia (

“Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects.

“The tags contain electronically stored information. Some tags are powered by and read at short ranges (a few meters) via magnetic fields (electromagnetic induction).”

“Others use a local power source such as a battery, or else have no battery but collect energy from the interrogating EM field, and then act as a passive transponder to emit microwaves or UHF radio waves (i.e., electromagnetic radiation at high frequencies). Battery powered tags may operate at hundreds of meters.

“Unlike a bar code, the tag does not necessarily need to be within line of sight of the reader, and may be embedded in the tracked object. RFID tags are used in many industries.

“An RFID tag attached to an automobile during production can be used to track its progress through the assembly line. Pharmaceuticals can be tracked through warehouses. Livestock and pets may have tags injected, allowing positive identification of the animal.

“On off-shore oil and gas platforms, RFID tags are worn by personnel as a safety measure, allowing them to be located 24 hours a day and to be quickly found in emergencies.[citation needed]

“Since RFID tags can be attached to clothing, possessions, or even implanted within people, the possibility of reading personally-linked information without consent has raised privacy concerns.”

Global RFID Market: Forecast to be valued at US$9Bn in 2014

From the Companies and Markets Website (

“Rapid growth is being reported for apparel tagging within the retail RFID market. In 2013, the application alone demanded 2.25 billion RFID tags. RFID tags in the form of tickets used for transit are also showing strong growth with 600 million tags in circulation in 2013. In several countries, the tagging of animals is also becoming a legal requirement which is driving demand in the use of RFID tags on animals such as pigs, sheep and pets. The animal sector has an estimated 375 million tags in circulation.”
