Bank cards include some data that allow us to use them safely. This is the case with the CVV, but what do those initials mean? We explain what they mean and how many types of CVVs we can find.
When we place an order online, if we decide to pay by credit card, the e-commerce retailer asks us for information including the CVV of the credit card. This is done as a measure to add an extra layer of security to our online purchases.
What is the CVV code?
CVV stands for Card Verification Value. This code is usually composed of a three-digit number provided by the companies that make the bank cards (American Express, Visa, Mastercard, etc.).
The CVV code is usually located on the back of the card, although in some cases it may be found on the front.
What types of CVVs are there?
There are two types of verification codes found on bank cards:
CVV1: this is the code that is encrypted in the card's magnetic strip, so it is not visible. That type of verification code is automatically read by the POS (Point of Sale) terminal when we make a payment or receive a refund in a shop.
CVV2: this is the three-digit code printed on the back of the card that we are asked for when making a purchase online. Those digits are not stored in the payment gateway and will therefore be requested each time we make a transaction.
What is a dynamic CVV?
There are now banks issuing credit and debit cards that do not have the CVV code printed on them. These are known as bank cards with a dynamic CVV.
This type of verification code changes from time to time, so in order to obtain it, card holders have to access their bank's digital banking service. Therefore, for each payment made, a new CVV is generated. This new validation code represents a further step forward in the safety of online purchases.
