Description
Radio-frequency identification (RFID) technology whereby digital data encoded in RFID tags is captured or identified by a reader via radio waves. EM-18 RFID Reader Module utilizes radio-frequency electromagnetic fields to transfer data, For the purposes of automatically identifying and tracking tags attached to objects. The tags contain electronically stored information. This EM-18 RFID Reader is a Tiny, simple to use RFID reader module.
