It is impossible to operate the machine without two keys, and the case lock prevents tampering with the signature die (which can be removed by key and locked up for safekeeping).
A separate switchlock prevents an imprint from being made by an unauthorized person.
In addition, a visual counter records the number of times the machine is used, and can be reset only when the case is unlocked.
An adjustable guide locates the signature precisely. Other wording can be printed with the signature.
