What is security code in debit card?

As someone who works in banking, I can explain this well. The security code has different names:- CVV (Card Verification Value)- CVC (Card Verification Code)- CID (Card Identification Number)It's not stored in the magnetic stripe or chip, which is why it provides additional security for online purchases. Even if someone gets your card number and expiration date, without the CVV they can't complete most online transactions. Always keep it confidential and consider covering it with a sticker if you're concerned about security. Your bank's fraud department will never ask for this code over the phone or email!

The security code on a debit card is the CVV (Card Verification Value). It’s usually a 3-digit number on the back of Visa/Mastercard or a 4-digit code on the front for Amex cards. It’s an added layer of security for online transactions. Never share it with anyone, because it can be misused for unauthorized payments.

The security code on your debit card (often called CVV or CVC) is that 3-digit number on the back of your card, usually on the signature strip. For American Express cards, it's a 4-digit number on the front. This code provides an extra layer of security for "card not present" transactions like online shopping. It's designed to verify that you physically have the card when making purchases. Never share this code with anyone unless you're making a legitimate purchase from a trusted merchant. It's different from your PIN, which you use for in-person transactions.
