RFID – Radio-frequency Identification used in industrial automation.

RFID

RFID – Radio-frequency Identification is the technology that uses R F I D-tags, basically an electronic R F I D-chip with an antenna, attached or implanted into goods, animals and humans, for identification purposes. On the other side R F I D-readers are used, which are basically radio-wave sending and receiving antenna's, sending a signal to the RFID-tag, and reading the signal that the RFID-tag sends back to the antenna. This makes it possible to track and trace goods, animals and also humans. A complete introduction into R F I D-technology can be found in Wikipedia.org. This web-page can be found here: http://en.wikipedia.org/wiki/Radio-frequency_identification .

This RFID-technology is also being used in industrial automation. Special RFID-tags have been designed to use in an industrial environment. Tags that can withstand not only high temperature variations, but also can withstand for example a constant heating and cooling cycle, without loosing the data in the RFID-tag. An example of Radio-frequency Identification in industrial automation can be found at Turck.de. Take a look at the following application example: http://www.turck.de/en/3522_modular_rfid_system_for_safe_ data_transmission_in_temperature_ ranges_up_to_210degrees.htm .

An article on the consequences of the use of RFID-tags, in our cloths can be found ate News.Cnet.com . Does constant tracking become possible, and what are the consequences of the abundant use of RFID-tags? This article tries to give you an insight in what could be possible. You can read this article here: http://news.cnet.com/2010-1069-980325.html.

When we are talking about RFID-technology, we are not only talking about the tags or labels, but also about the readers or antenna's. These RFID-antenna's vary according to their application, and make it possible to read tags only a few millimetres away, up to meters away, when the tags are standing still, or even when the tags are passing by, on the fly as we say. An explanation on how RFID-technology works, can be found at HowStuffWorks.com.
