Currently, if a smartcard user enters a bad PIN three times, the smartcard is blocked, and the error feedback is "Bad PIN":

Only on the 4th try, the user will notice, that the smartcard is blocked:

From user perspective it would be best to know, that a device is blocked the moment it happens, because it requires (preferably immediate) user action to resolve the situation.
If a user happens to stop after the 3rd try, it will break the next workflow, which could be a critical situation, and the error might not be associated with the cause, if enough time has passed.
