RFID Technology – The technology behind RFID, or how RFID works.
RFID Technology
RFID Technology – Some basic explanation on how RFID works can be found a Wikipedia.org .Radio-frequency identification uses devices called tags, whom are basically passive components.These tags are then energized and activated, with electromagnetic waves, generated in an other device. This device is called the interrogator, reader or antenna. The reader reads the code that is on the tag, and with more modern tags, is also able to write information on the tag. This technology derived from military applications, knows many useful industrial applications. Complete information can be found on the following web-page: http://en.wikipedia.org/wiki/Radio-frequency_identification .
Abuse of RFID-technology always lures around the corner, that is why governments have been creating a proper policy for the use of this technology. The Canadian government gives us an RFID fact sheet, where possible privacy concerns are listed. Since RFID tags are becoming smaller and smaller, they can be embedded almost anywhere. This creates the possibility of tracking persons without a person knowing it, breaching her or his privacy. You can read this RFID fact sheet by the Office of the Privacy Commissioner of Canada here: http://www.priv.gc.ca/fs-fi/02_05_d_28_e.cfm
On HowStuffWorks.com you will be able to read an article that explains How RFID Works. This article gives an overview on the different types of RFID tags used in supply chain management.
