RFID Tags, Tagging, & Smart Labels - Radio Electronics
The range of active RFID tags can be many metres - often 30 metres or more.
As battery power is required, this may allow much greater functionality to be incorporated.
An active RFID tag cannot function without battery power. This limits its lifetime, or requires maintenance.
RFID active tags are much more expensive to manufacture.
An active RFID tags will be physically larger than a passive one...
What Is the Purpose of RFID? | eHow
Radio Frequency Identification (RFID) is a technology designed to allow objects, animals and even human beings to be identified, located, and tracked using radio frequency signals. The history of RFID can be traced back to World War II, when it was used by the British to identify friendly aircraft. The technology has developed over the years and is now used in a wide range of...

Not surprisingly, IT Asset Managers have been asking more and more about the use of RFID to reduce the time and effort tracking assets, especially by implementing RFID technology in as many places as possible. As prices drop on RFID technology, the benefits become more and more realistic.
A customer recently asked me how much he...
RFID Centre - RFID
RFID is a general term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object wirelessly, using radio waves. This is sometimes referred to as contact-less technology and a typical RFID system is made up of three components: tags, readers and the host computer system.
Tags - An RFID tag is a tiny radio device that is also referred to as a...

RFID systems can use a cellular system called Time Division Multiple Access (TDMA) to make sure the wireless communication is handled properly [source: RFID Journal ].
Passive RFID tags rely entirely on the reader as their power source. These tags are read up to 20 feet (six meters) away, and they have lower production costs, meaning that they can be applied to less expensive merchandise. These...

Why use RFID - ThingMagic.com
There are multiple reasons one would want to use RFID:
Use RFID if you want to wirelessly identify something without line of sight. Line of sight means that one could draw a straight line going directly from the reader to the object without interruption. This is literally what is done for bar codes via a laser, but mirrors are used to make the laser look a little fancier. If the laser can't...

Hitachi Develops World’s Smallest RFID Chip
The Japanese giant Hitachi has developed the world's smallest and thinnest Radio Frequency Identification (RFID) chip. Measuring only 0.15 x 0.15 millimeters in size and 7.5 micrometers thick, the wireless chip is a smaller version of the previous record holder - Hitachi's 0.4 x 0.4 mm "Micro-Chip". The company used semiconductor miniaturization and electron beam technology to write data on the...

Arduino HF/UHF RFID Reader
I'm looking for a HF/UHF RFID reader I can interface with via Arduino. I've been using 125kHz solutions which, though they work great, just don't have the range I'd like them to.
Ideally, I'd like an RFID reader that can pick up a passive RFID tag that is in a wallet/pocket and within 1-2m, without the user having to present the tag to...

National Oilwell Varco
Most wells lose production pressure after only 30 percent of the reservoir is extracted, leaving behind rich reserves. The U.S. Department of Energy and World Energy Council estimate that hundreds of billions of barrels of oil exist in old wells.
Up to 50 percent more oil can be tapped by increasing reservoir pressure via water injection and other methods. Global water injection requirements are...
