TELTONIKA TELEMATICS iButton key - magnetic. Compatible with iButton reader CZ0M 120C

Driver identification in fleets often fails due to fragile cards, forgotten PINs, or readers that cannot withstand harsh environments. The Teltonika iButton Key solves this by providing a rugged, magnetic identification token that works seamlessly with the Teltonika iButton reader CZ0M 120C. Simply touch the key to the reader and the unique 64-bit ID is transmitted instantly over the 1-Wire protocol.
