Do all credit cards require a pin number?

No, not all credit cards require a PIN number. While many credit cards have an associated PIN for use in specific situations such as cash advances or making purchases at unattended terminals, such as those found at gas stations or certain vending machines, most credit card transactions can be completed without a PIN. Typically, credit card transactions are authorized by providing the card number, expiration date, and security code (CVV) on the back of the card, along with a signature or online verification. However, the use of a PIN may vary depending on the card issuer, card type, and specific circumstances.
