This basic RFID Tag is used mostly as an identity card. The card comes with a 40-bit unique ID and cannot be re-programmed. This is a slightly flexible, blank, white card with a gloss finish.
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.
