CDVI Robust Mifare Smart Fob The METAL is a tag-style access credential equipped with the MIFARE® Classic communication protocol. With a robust metal and polycarbonate case, the METAL is ideal for attaching to lanyards or keyrings for greater convenience. The MIFARE® Classic protocol enables additional information to be stored and used on the tag other than its unique identifier for access control purposes. For example, payment information for on-site vending machines can be stored.
