This RFID tag is a white plastic square with adhesive backing. The tag continues to operate normally when attached to metals, unlike most standard RFID tags. The tag contains a unique ID that can be read by the 1024 – RFID reader at a distance of 8cm or less.
This tag uses the EM4012 protocol (part of the EM4100 series) and can be read by any of the RFID readers in the table below. If you're using a different RFID reader, make sure it's designed to work at 125 kHz and supports this tag's protocol.
