Nowadays, it is not necessary to carry a wallet. Since a smartphone, among its wonderful utilities, offers the opportunity to make payments through applications. Thus, the customer can, from paying for a coffee in a shopping center to buying shoes in an online store anywhere on the planet. All this, only, using your smart terminal, either iOS (Apple) or Android.

But on many occasions, the user is unaware of the usefulness of some of the digits, such as the CVV code, which is part of their credit or debit card.

These digits help make online purchases safer and therefore, reduce the number of fraudulent uses of them. This application also allows users to check the movements of their credit and debit cards, activate and block their cards for theft or loss without having to go to the branch. In addition to facilitating the opening of a digital card to make purchases on the internet.

So what is CVV Code on credit cards?

In addition to the main digits that give the number to the card itself, there are two more groups of numbers that fulfill strict security functions. These two codes are the expiration date, expressed in MM / YY (month/year) format – which indicates the card’s deadline for use – and the CVV or CVC Code (Card Verification Code). Both serve to demonstrate that the person making the purchase has the card in their possession and not just the number, thus avoiding possible fraudulent purchases.

The CVV or code of verification or validation value (Card Verification Value) is the group of 3 or 4 digits located on the back of the card. The name of this code differs between credit card companies, as it can also be called a card verification code or CVC, card security code, or personal security code.

There are two basic types of credit card verification codes

Both are generated by the card issuer at the time of issuance and are:

CVV type 1: The code is encrypted on the second track of the credit card’s magnetic stripe and is used for transactions in which the card is physically present.

CVV type 2: It is the code most frequently used by cardholders since type 1 is read automatically and the cardholder is rarely aware of its use.

This code is requested by the sellers in transactions in which the card is not present. These are transactions carried out over the internet, telephone, or other telematic means.
