Let’s look at credit cards this time. Have you ever wondered what exactly that is of CCV or CVC? What is it for? Because it is important? Do you need it and do not know where to consult it? We clear your doubts.
Card Verification Value
CVV stands for Card Verification Value: a numerical security verification code, consisting of three or four digits, linked to a credit card. Some debit cards also have it.
There are companies that call this security code CVC (Card Verification Code), CVD (Card Verification Data), CVN (Card Verification Number), CSC (Card Security Code) or CVVC (Card Verification Value Code). But they are simple denominations since they all refer to the same. This is the name that each company gives to that set of numbers, although most use the acronym CVV or CVC.
CVV can be of two types. The CVV Type 1 is the one whose code is in the magnetic stripe of the card and is read by readers of establishments (POS Terminal, TPV), automatically, when we introduce them to make a purchase or receive a return. As consumers, we are not aware of its use.
What we are aware of using, often essential for our operations over the Internet, is the CVV type 2, which is located on the front or on the back of the card.
Each time we make a transaction with it electronically, the seller, organization or company may request that we indicate the CVV numbers in the corresponding box enabled for this purpose, in the virtual POS, to ensure that we are the cardholders and we have it in hand when performing the operation. Its purpose is, therefore, to avoid fraudulent uses with it. This is the code we refer to generically when talking about CVV.
How to know the CVV of your card
Cards such as Visa and MasterCard, which have a three-digit CVV, show it on the back, the three final numbers is located in the band where you must sign it or next to it. In the case of American Express cards, whose CVV is four digits, you will find it in relief, located on the right, on the front, in isolation. Often, in American Express, the CVV is called CID (Card Identification Number).
However, you have to keep in mind that the need to include these digits or not in Internet transactions is not mandatory in all countries, so you can find e-commerce companies that do not require it.
You should also know that, while the card number remains unchanged over time, each time we renew it, either by replacement or loss, the CVV is modified. You should not provide this code to anyone and you only have to use it on websites that are safe and reliable.
Keep in mind that with the card number and CVV it is very easy to clone it, impersonate and make all kinds of transactions on your behalf, so cyber criminals look for all possible ways to get those three or four digits.
