If you've ever made an online payment with your bank card, you've probably come across a CVV number. But what exactly does this number mean and why is it so important? In this blog post, we explain what a CVV number is and how it works.

What is a CVV number?

The CVV (Card Verification Value) number is a three-digit security number that you can find on the back of your bank card. It is sometimes also referred to as a CVC (Card Verification Code). If you have an American Express card, it's actually a four-digit number on the front of the card. This number was introduced to increase the security of online payments and ensure that you are actually in possession of the card.

Why is the CVV number so important?

The CVV number plays a crucial role in preventing fraud. Unlike your card number and expiration date, which are often printed on receipts, the CVV number only ever remains on the physical card. It is never stored on receipts and must not be included in merchant databases. This makes it much more difficult for fraudsters to misuse your card details.

When you shop online or make a payment over the internet, the CVV number is used to verify that you are the real cardholder. Without the correct CVV number, a transaction often cannot be completed, which increases your security and that of the merchant.

How should you handle your CVV number?

It is important that you always keep your CVV number confidential. Only provide it when paying at a trusted merchant.

Keep your bank card safe and avoid taking photos of it or storing the number somewhere where it could fall into the wrong hands.

The CVV number is an important part of the security measures that protect your bank card from unauthorized use. It's a simple but effective way to ensure that your online payments are secure. Remember to never give your CVV number to unauthorized third parties and to protect your bank card carefully.

By following these tips, you can be sure that your finances and personal data are well protected.
