RFID
iTech is certified by the leading RFID technology companies and has successfully installed & supported various RFID tracking systems since 2001.
RFID uses low-power radio signals to exchange data wirelessly between chips and readers/encoders. No direct line of sight is needed between the tag and read/write device, eliminating many of the labor and item-orientation requirements associated with other forms of automated data collection. RFID readers can simultaneously recognize and process hundreds of tags within their read fields.
RFID tags consist of an integrated circuit (IC) attached to an antenna - typically printed or etched conductors on a thin plastic sheet. Data is stored on the IC and transmitted through the antenna. Tags may be thinner than a grain of rice or as large as a brick. RFID tags are either passive (no battery) or active (self-powered by a battery). Data transmission speed and range depend on the radio frequency, antenna size, power output, and interference. Tags can be read-only, read-write, or a combination, in which some data (such as a serial number) is permanently stored; while, other memory is left available for later encoding or to be updated during usage.
In passive systems, which are the most common, an RFID reader transmits an energy field that "wakes up" the tag and provides power to the chip, enabling it to transmit or store data. Encryption algorithms ensure security and the integrity of the data passing between the tag and reader protect transmissions. In active systems, batteries typically are used to boost the effective range of the tag. Active tags may also transmit a signal periodically, much like a lighthouse beacon, so that data may be captured by readers distributed throughout the facility.
