PIN change


PIN protects secrecy of the smart card. Card protected information is available only if correct PIN has been inserted.

It's recommended to change PIN from time to time (for security reasons):

It is not supposed to insert current PIN value when card's PIN has not been set; the user inserts just new PIN value twice (for verification).

The card's PIN must not be blocked. It's impossible to change blocked PIN, it can be unblocked using PIN Unblock option.

PIN change option is accessible if the card is selected in the information tree.
