RFID Reader Modules are in stock at Tenco Electronics. An RFID reader is a radio frequency device that emits a signal through an antenna. This signal is received by RFID tags that respond to interrogation by the reader. Responses are read by the reader, and through a variety of protocols the reader can communicate with all the RFID tags in its field. Readers generally take three forms. Portal readers are fixed in one location; RFID tags pass through them and communicate with the reader. Tenco offers inventory, pricing, & datasheets for RFID Reader Modules.
