RADIO FREQUENCY IDENTIFICATION
Radio frequency identification (RFID) is the wireless
non-contact use of radio-frequency electromagnetic fields to transfer data for the purposes of automatically identifying and tracking tags attached to assets. All systems require readers, antennas, and tags in order to function.
International Loss Prevention Systems RFID technology can be used in hundreds of applications, starting as a simple security solution to a complete inventory management solution.
RFID Antennas are a necessary element in any RFID system; however, they are simplistic devices that use power from the reader to generate a field allowing the reader to send and receive signals from RFID tags. Antennas vary in size, gain, IP rating, polarization, and connector type. The price of antennas ranges from approximately $100 to about $1,000+ depending on the type, size, and level of ruggedness. Selecting the right RFID antenna for your application is crucial to the success of your system.
An RFID tag, in its most simplistic form, is comprised of two parts – an antenna for transmitting and receiving signals, and an RFID chip (or integrated circuit) which stores the tag’s ID and other information.Which one you choose will depend on how and where you deploy the reader.
An RFID reader is the brain of the RFID system and necessary for any system to function.
Readers, also called interrogators, are devices that transmit and reciprocate radio waves in order to communicate with RFID tags. RFID readers fall into several classes – fixed RFID readers, handheld RFID readers, and integrated RFID readers.
