A Personal Identification Number (PIN) is a numeric code used to authenticate an individual’s identity, primarily in financial transactions such as ATM withdrawals and online banking. It typically consists of four to six digits and should be kept confidential to ensure security. Users enter their PIN alongside a card or account number to access their accounts or authorize transactions. PINs are designed to provide an additional layer of security against unauthorized access.
