Offline TAN

The offline TAN section is used for three different tasks:

1. Generating TAN registers against level 3 TAN prefixes.
2. Viewing a log of the TAN registers - the "extract history"
3. Invalidating TANs - this might be used if, for example, the TAN register were lost and the TANs needed to be invalidated.

Navigate to the Offline TAN section using the TAN System menu on the left side of the screen.
