UM-WIE is a module working on the principle of contactless collection of unique identification data from the Unique transponder (RFID). These data are appropriately processed and forwarded in serial form to the master device. Additionally, the reader can be connected to a buzzer and LED signaling notifying about correct reading of the transponder.
