The appearance of the first bank card and the ATM, more than 50 years ago, was a revolution in the world of banking. Since then, the number of cards has risen unstoppably.
To try to minimize the risks involved in having a card, whether credit or debit, entities have developed different security methods to guarantee that our card is only used by us.
One of the most important is the implementation of the card security code, better known as the CVV Code. In VISA and Mastercard cards, the code is found on the back of the card, near the space for the holder’s signature, and consists of three digits.
And the CVV location on AMEX can be found on the front right of the card and has one more number.
But what is it exactly?
It is a security number for transactions in which the card is not used physically. Thus, you will have to use it every time you buy online. The objective is to avoid that, in the event that someone gives your card number, they cannot use it because they do not know said code.
The guarantee of this security measure is that nobody knows the number. Before making any purchase online, and entering your card number and CVV, make sure your connection is protected.
To do this, check that to the left of the URL there is a green bar that specifies that the page is secure. Remember: it is very important that no one knows this number. Never provide it on any website unless you are in a protected environment.
If your card has been lost or stolen, we recommend that you cancel it as soon as possible. Don’t worry: the CVV Code is unique for each card, so your money will be safe.
In addition to Visa CVV Code, 2-step authentication has been developed in recent years, an extra security measure. As the Internet User Security Office explains, with this measure we make it more difficult for an unauthorized person to operate with our card.
The typical two-step authentication methodology is, in turn, very simple. When making a purchase with the card, we (normally) receive an SMS with a code on our phone that we must enter in the payment process.
Before making any purchase, examine the website where you are going to carry out the operation, use secure means of payment, and review the banking operations.
Remember also not to operate through public Wi-Fi networks to carry out this type of operation and always access pages through the URL that you have entered into the system. Do not trust redirects or direct links.
