If you have ever made purchases via the Internet, then most likely you have encountered the need to enter a security code. Everyone should know this parameter. So what is a card security code? That's what we're talking about.

Understanding terminology

If we talk about what a card security code is, it should be noted that it is a set of characters separated from the card number and used to make one-time payments during the purchase of goods via the Internet. Different means of payment usually have different character sets. The security code on the Visa, Master Card, JCB, DinersClub cards usually consists of three unique characters that are placed on the reverse side, namely on the signature strip. American Express cards use a four-digit number placed above the main number on the front.

How does it work?

So, what is the security code of the card, you already understand, now it's worth touching on the issues of working with it. The existing rules are spelled outso that the merchant does not store this character set after the transaction is completed, nor is he required to use it to receive payments. However, the situation is such that many banks do not agree to conduct transactions without entering this code, so payments do not go through, and customers are unhappy. Since a bona fide merchant is obliged to forget the security code after the transaction, purchases using such a tool are not suitable for implementing recurring payments.

So you know where the security code is on the card, so you can shop online. For users who shop online regularly, it is worth saying that a PIN is not needed. Entering the security code is the only way to confirm the payment. When entering any personal data on the network, in no case do you need to provide a PIN code.

Safety

So, you must not disclose the Visa card security code, its number, credit limits, card validity period in response to requests that may come via SMS messages, to your e-mail, as well as on the pages of sites that are not involved in sales. Payment for services in the network should be implemented through a separate, prepaid card. And in this case, you should not store a lot of money on it. If you have a significant balance, you should set a limit on debit transactions per day.

There are signs that are immediately evident, indicating that the site is fraudulent - a primitive design, an abundance of banners and activelinks of questionable content. Another precaution is to install anti-virus software on your computer and keep it up to date.

Visa International

The bank card of this brand allows its owners to withdraw cash, purchase goods at retail outlets, pay bills in cafes and restaurants, and pay for online purchases. Such banking instruments are in great demand, because it is a convenient and fairly safe means of depositing/withdrawing monetary assets.

A Visa International credit card can be purchased at any financial institution. In practice, it becomes clear that in order to obtain it on the most favorable terms, you need to familiarize yourself with the terms of lending in three or more banks. You should pay special attention to the limit of funds, the size of the credit rate, the maturity of the debt and the credit limit.

Features

Becoming the owner of this truly financial miracle, it is worth remembering that the attackers have recently learned how to fake any credit card very quickly. Therefore, it is recommended not to trust anyone, and also not to show your card. When withdrawing funds using an ATM, be sure to check if there are any reading pads on the receiving device. And the security code of your card should be protected even more carefully.

So, if we talk about what a Visa card security code is, it should be noted that it has the working name CVV2. It is presented in the forma set of characters placed on a magnetic stripe. Its main purpose is the ability to make one-time payments via the Internet.

Conclusions

All of the above indicates that in practice, the introduction of a security code does not contribute at all to improving the level of security, but it is guaranteed to cause confusion. If the security code is entered incorrectly, payments are not processed, and this causes dissatisfaction among bank customers. Recently, this is why most people prefer prepaid credit cards, since they are used to carry out transactions that do not require the user to enter a security code. This trend has spurred the development of a completely new technology, 3-DSecure, designed to make credit cards similar in all functions to electronic payment systems.
