Device Activation blocking and Unblocking

The blocking of the activated device happens, when the user fails to authenticate the configured maximum attempts (five is default), whether f.e. by entering the wrong PIN code or by failed biometrics. When blocking happens, the state of the activation changes to BLOCKED.

The unblocking is performed through an external trusted channel, such as internet banking, customer support, or a back-office system.

After successful unblocking, the activation transitions back to the ACTIVE state and normal operation is restored.
