How RFID works? Radio frequency identification technology is an automatic way to collect data on products, places, and transactions with a minimum of human intervention. A basic RFID system consists of a reader and an RFID tag that carries the data. The tag transmits a powered radio signal that the reader receives. The data is then stored in a main computer or database for processing purposes. Are these systems new? No, RF identification has been around since the late 1960's. What are some uses? Vehicle security, toll collection, inventory control, building security, and library systems, tickets, bar code replacement. Are there power restrictions on RFID Devices? Yes, the FCC is the governing body for RFID devices. They set the guidelines for power output to ensure safety. What are the advantages of using RFID? RFID often provides automatic identification and announcement, and better access controls. This saves man hours and reduces operating costs. Do consumers benefit from RFID? Ask yourself if the following are benefits: Stolen merchandise recovered, Gas Passes, Toll Booth Passes, anti-theft devices in your car, and of course, authenticating and securing your child's school dismissal. Can RFID tags be tracked by Big Brother? Not likely. This is a short-range radio technology. What are the health risks of RFID TAGS? RFID tags are supposed to be no more dangerous than a regular radio.
