PIN verification
Secret number check
PIN verification is the process of confirming that a personal identification number entered by a user matches the one stored for their account or card.
It's a basic security step at ATMs, point-of-sale terminals, and electronic devices: The transaction failed after three unsuccessful PIN verification attempts.
The system checks whether you know the secret code assigned to you.
