Nearest replacement is RFI4010_0 – PVC 18mm Disc
A small plastic RFID tag. This versatile tag is round and flat to be stuck onto anything. We also carry a large disc tag and two with adhesive backing. The tag contains a unique ID that can be read by the 1024 – RFID reader at a distance of 5cm 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.
