The three primary components that make RFID “Work” are Tags, Readers, and Software that collects data from the readers and helps turn it into actionable information.
RFID Readers are devices that read/write data from/to RFID tags and transfer this data to back end IT systems. Fixed Readers are mounted to a specific location (e.g. a dock door or similar portal) and generally require one or more external antennas and associated cabling for an increased read area. Less powerful Mobile readers offer greater flexibility but with a decreased read range as compared to fixed readers.
