environment—it is not a technology in which 'one size fits all' applications. Three primary frequency bands are being used for RFID: Low Frequency (125/134KHz)—Most commonly used for access control, animal tracking, and asset tracking. High-Frequency (13.56 MHz)—Used where medium data rate and read ranges up to about 1.5 meters are acceptable. This frequency also has the advantage of not being susceptible to interference from the presence of water or metals. Ultra High-Frequency (850 MHz to 950 MHz)—offer the longest read ranges of up to approximately 3 meters and high reading speeds. Figure 6 illustrates the different frequencies that are used for RFID Tags. Figure 6.

However because of their different structure, SMBs need to carefully determine whether or not an RFID system is the answer to their organization's problems.
...
RFID systems, typically, include tags containing microchips and tiny radio antennas that can be attached to products. The device transmits a unique identifying number and sometimes associated information on the tagged product to an electronic reader. The system is often used for asset tracking and management by large organizations. Technology developers, integrators and users who attended the recently concluded RFID Live! Canada conference in Toronto share some pointers aimed at helping small companies ease some RFID implementation pains. 1. Get educated Because most SMBs often have limited budgets and personnel, companies considering RFID deployments should research the technology before purchasing equipment or software. "There's no need to jeopardize resources especially when the budget is tight," said Pierre Malboeuf, president

This paper concentrates on the possible applications for the technology within the water industry where a business benefit is evident, and it describes the practical aspects that must be considered in implementing a scheme.

Radio frequency identification (RFID) is a technology bubble ready to burst according to a new report by Dublin-based firm Heavey RF.
The firm, which
...
provides radio frequency products such as handheld scanners, has published a study entitled RFID.Bomb?
"History is littered with large technical blunders; RFID in the supply chain is potentially one of the biggest," said Ronan Clinton, managing director of Heavey RF.
The report claims that RFID is unlikely to replace bar coding as a means of identifying goods. Heavey RF carried out the study after receiving several queries from clients wishing to deploy RFID in their business.
"I'm fed up with companies telling me they want to implement RFID in their business," Clinton told ENN.
RFID uses computer chips to store information. The benefit over conventional methods of tracking items, such as barcoding, is that comparatively large volumes of data can be stored in a tag and line of sight is not necessarily required to scan the item. Indus

important technology trends of the last several years. The consumer effect is when technologies popularized by consumers find their way into corporate use, like iPods or social networks. In a gradual about-face, RFID, which has been a corporate technology from its inception, is finding its way into the consumer market. AT&T is responsible for helping to mainstream RFID, according to a news story by my colleague Elena Malykhina: AT&T on Wednesday began providing radio-frequency identification and GPS-based products and services that schools can use to track students, assets, visitors, and their staff. AT&T's RFID application is designed to work in conjunction with GPS-based mobile resource management services, as well as the carrier's wireless data network and hosted applications. That's good news for RFID and its advocates, because th

Abstract
U.S. Customs and Border Protection (CBP) employs Radio Frequency Identification
(RFID) Technology that is to be used in cross border travel documents to facilitate the land
border primary inspection process. A unique number is embedded in an RFID tag which, in turn,
is embedded in each cross border travel document. At the border, the unique number is read
wirelessly by CBP and then forwarded through a secured data circuit to back-end computer
systems. The back-end systems use the unique number to retrieve pers

other established applications and technologies. There were several technological milestones and standards developments, including a few that will likely have a strong influence for years to come. RFID technology perhaps received more mainstream media coverage than ever before, but much of it was misguided or simply inaccurate. RFID Update has chronicled these developments on a near-daily basis. Here we present what we consider the top 10 developments in the RFID industry in 2007, with our insight and links to articles that provide more background information. #10 -- The Time is Now for Real-Time Location Systems Adoption was strong for real-time location system (RTLS) technology throughout 2007, and enthusiasm was even stronger. Numerous new implementations -- not pilots -- were announced throughout the year, along with technology and

...
RFID tags are claimed to be readable through an instrument case, and as they support global frequencies, it means that electronic systems can be tracked down the supply chain and through their lifecycle. The tags can use the PCB ground as an antenna, but connect to the antenna pattern via inductive coupling. This is said to eliminate the need for an electrical connection between the tag and the board, and allows the tags to be placed accurately. Abacus states that legislation on the recycling of electronic systems has created a need to accurately identify individual electronic systems from manufacture through distribution to end customer and disposal. They explain that RFID tags can be updated with new information as a product progresses through the manufacturing and shipment process, and therefore are ideal for this requirement. Murat
