The Skinny on RFID by John Hanson
RFID is the abbreviation for Radio Frequency Identification. RFID is a method used to store and retrieve data using RFID transponders or tags. RFID tags have antennas that allow them to accept and respond to queries from the RFID transceiver. There are passive and active RFID tags. ... Active RFID tags have a longer range and larger memory capacity than passive RFID tags and may therefore be able to store a significantly higher amount of information. ... Having an RFID system will allow data to be transmitted by a tag, which is then read by the RFID reader and processed in accordance with...

It's a Small RFID World After All by Sally Bacchetta
Trolley Scan of Johannesburg, South Africa has announced the delivery of the first commercialized version of "RFID-radar" to a European IT company. RFID-radar enables a system user to accurately measure the distance travelled by a signal from a transponder to a reader. ... Conventional RFID has a fairly limited read range. ... That ticket is RFID-chipped to track your entry and exit through the RFID-rigged gate. ... Until now, you would have had to install RFID readers every 10-25 feet to achieve this degree of scrutiny.

RFID: A Closer View by Sally Bacchetta
Within the last few years RFID (Radio Frequency Identification) has steadily migrated from the inner circles of science and technology into the public consciousness. RFID is now well-integrated into the food you eat, the clothes you wear, the car you drive... ... When a tag passes within range of an RFID reader, proprietary information is transmitted through the antenna to the reader, which in turn feeds the data to a central computer for processing. ... RFID has been described as “wireless bar coding”, but in fact, even basic RFID far surpasses bar coding capabilities.

RFID: When You Don't Even Know It's There by Andy Reed
RFID (Radio Frequency ID) enables wireless data capture and transaction processing. Our last column discussed proximity applications, used primarily for access control. This time, we'll take a look at what are broadly defined as vicinity, or long-range applications, used for product tracking,... Similarly, RFID is already being used to track passenger progress through airports, reducing the number of passengers arriving late at the gate and in so doing ensuring that planes leave on time." I anticipate a wider range of uses for RFID systems in the future.

RFID: Coming to an Application Near You by Andy Reed
Now that we're six years into the third millennium, it's time that some 21st-century technology is coming of age. It's a slow process, but it's inexorable, so if you're not familiar with it, here's a short overview of what it is and what to expect from it. ... Systems can also be designed so that a computer's software will not operate off-site: unless the RFID chip in the laptop is within radio range of the host computer (at the office), it simply won't turn on. ... Called RFID: Applications, Security, and Privacy , it's a long read (608 pages) and thoroughly covers wide-ranging questions...

RFID, Its Implications And How To Defeat by Jon Winthrop
Imagine a future in which your every belonging is marked with a unique number identifiable with the swipe of a scanner, where the location of your car is always pinpoint-able and where signal-emitting microchips storing personal information are implanted beneath your skin or embedded in your... Pharmaceutical tracking has long been held out as one of the flagship applications of RFID in the short term, yet just some 10 medications are expected be tagged using RFID technology on a large scale in the U.S.

Use of RFID Technology in Libraries: An Automated Metheod of Circulation, Security, Tracking and... by Syed Mohammad Shahid
1. Introduction RFID is an acronym for Radio Frequency Identification. It is a technology that allows an item, for example a library book to be tracked and communicated with by radio waves. This technology is similar in concept to a Cell Phone. Radio frequency identification, or RFID, is a... There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag).

Pros and Cons of RFID Technology by Brian F.
I. RFID Advantages Radio Frequency Identification provides a valuable service that is capable of revolutionizing the way companies track products. There are many benefactors of this technology: the military, retailers, suppliers, consulting firms, producers of the technology, and consumers. ... While 900 MHz appears to be the best frequency due to its long read-range capability, 13.56 MHz is still used delaying the standardization of global frequency for RFID. ... However, when RFID tag prices fall, companies like Wal-Mart and Target plan on using RFID tags on individual products which...

Information in the Next Five Years by Ena Mwangama
Impact of Radio Frequency Identification Technology The Environment consist of the all elements that are outside the system under consideration, and which it must take as given .The environment also include all the external impositions and constraints other than those imposed by the ownership. ... The scary part of the use of RFID tag is that products bought with an RFID tag on it could all be traced specifically to the buyer just with the help of the tiny chip inside. ... RFID will have a massive impact on the technical side, as the company will need to change the whole infrastructure...
