What is the CVV of a card?

The CVV (Card Verification Value) is a security code found on credit or debit cards. It is designed to confirm that the person using the card is physically in possession of the card. 

This code is usually three or four digits long, depending on the type of card you have. On most cards (such as Visa or Mastercard), the CVV appears on the back, next to the space for the signature. On others, such as American Express, the code is on the front.

What is the purpose of the CVV?

The CVV plays a crucial role in digital transactions. When you make a purchase online or by telephone, you will be asked for this number to validate that the transaction is legitimate. It is an additional security measure to protect your bank details. 

For example, even if someone obtains your card number and expiry date, they will not be able to complete a transaction without the CVV. This reduces the risk of fraud in purchases where a PIN is not used, such as online purchases. 

Does the type of card play a role?

The CVV is present on almost all credit and debit cards, regardless of the institution or type. However, the format may vary: 

• Visa and Mastercard: Three-digit code on the back. 
• American Express: Four digits on the front. 
• Virtual cards: Some also generate a temporary CVV that changes regularly for added security. 

Are there different types of CVV?

CVVs can be divided into two types: 

1. Static: This is the fixed number printed on the card. 
2. Dynamic: On virtual cards, this code can change after each transaction, which adds an extra layer of security. 

The importance of keeping your CVV safe

While the CVV is a security tool, it is also essential that you take steps to keep it safe: 

• Don’t share it: Only use it on trusted websites and avoid sending it via messages or emails. 
• Check the security of the website: Make sure that the page where you enter the CVV has a padlock in the web address bar (https). 
• Take additional measures: Activating notifications for each purchase or using virtual cards can increase your protection. 

 The CVV is a small but essential feature of your cards. Keep this number private and use it only when necessary. This code helps you to protect your digital transactions and prevent fraud. By knowing what a card’s CVV is and how it works, you can shop online with greater confidence and security.
