Credit cards have various security measures that protect the user from many dangers, such as theft or fraudulent use of the card. Among these security measures is the CVV (Card Verification Value) or CVC (Card Verification Code), a security code that greatly minimizes the risk that someone may use our credit card without our consent.
In this article we will give all the information that exists about the CVV so that there are no doubts about its meaning, its function and its importance. From where it is located, to how many digits it is composed, like the types of CVV that exist today in credit cards. If you also want to know what the rest of a card number is for, you can also check the following article .
What is the CVV or CVC?
The CVV or CVC is a code of three or four numbers that is on the back of any credit card , and is an additional security measure used to verify that the user who is buying something with the credit card has it in its power That is why its use becomes important in purchases made telematically, either through the Internet or by phone. Generally, to confirm the purchases made by these means, both the CVV and the expiration date of the card are requested.
However, there are different nuances. Depending on the issuer of the card, this code can be called CVV or CVC, acronyms that we have explained above what they mean and which are the most widespread. But we can also find other acronyms to refer to this code, such as CCV (Card Code Verification), CVN (Card Verification Number), CSC (Card Secutiry Code) or CVD (Card Verification Data), among other variants.
In addition, the number of digits can vary between three and four, but also its placement in the credit card. In the case of VISA and Mastercard, the CVV is composed of three numbers and is located on the back of the card . However, in American Express the CVV consists of four digits and appears on the front of the card .
What types of CVV are there?
But in addition to the usual CVV that everyone knows and that we have already explained, there is another type of CVV that is related to the magnetic bands that previously had the cards. In this way, we can find two types of CVV at present :
- CVV type 1 : This CVV is found on those credit cards that have a magnetic stripe , and its function is to assure the financial institution that the credit card is present at the time the transaction is carried out . At the moment in which the card is inserted in the point of sale terminal, the device obtains the CVV of the magnetic strip and sends it to the issuer of the card so that the operation is authorized. The problem with this type of CVV is that it can be easily copied in case of a cloning of the credit card. The digits are the same as the last four numbers on the card.
- CVV type 2 : This CVV is the one we have referred to in this text, and the most frequent one at present . It is printed in plain text on the card and is responsible for confirming that the user making the purchase has the original credit card in his possession, something that is very useful for operations carried out on the Internet. The number is formed by a mathematical algorithm, and can not be cloned together with the card.
How does the CVV increase the security of the credit card?
As we have said before, the CVV is a code that increases the security of the credit card by requiring the buyer to prove, entering the numbers at the time of formalizing the transaction, which has the credit card in its possession and not only the number. In fact, the credit card CVV has no relief of any kind, as it is printed on the card by flat printing. In this way it is very difficult for anyone to know the number by cloning the card, carbon copies or other procedures.
The only way to know the CVV is by owning the credit card. The CVV does not appear on any invoice, receipt or bank statement, so it is very important to try not to leave a trace anywhere about this number. In addition, when shopping online, we recommend paying attention to the website where the operation is going to take place, since it is important that the portal offers all the guarantees of security and protection of basic data so that we do not suffer in any way. case the theft of the data of our card.
Other additional validation methods
But the CVV is often not enough to completely protect the card against the risk of fraudulent use by third parties. That is why credit card issuers such as VISA or Mastercard offer security systems such as Verified by VISA or MasterCard SecureCode . These systems represent an additional security barrier when making purchases online, asking the buyer to enter the card number, the expiration date and the CVV to finalize the transaction, at which time VISA or MasterCard send a Confirmation SMS to the holder’s mobile associated to fully validate the operation. In this way, this two-step process ensures that the buyer has both the credit card and the mobile phone authorized to receive these security codes.
