The card security code (CSC) is designed to verify the authenticity of a credit or debit bank card when paying for goods or services on the Internet. This secret code is better known as CVV2 (for Visa cards) or CVC2 (for MasterCard cards), consists of 3 digits and is present on the back of almost all bank cards with some exceptions. Consider further the main purpose of the security code and its location on the cards of various payment systems.
What is security code CVV2, CVC2, CID
If you made payments on the Internet at least once (only not through the Internet bank, but, for example, when paying on the website of an online store or when replenishing a cell phone account), then you had to get out your credit (or payment) card and fill out a form payment on the site with its details. Usually you are asked to enter the card number, the name of the holder, the expiration date and the secret code.
You may come across different names for this code, but its purpose is always the same - it is an additional protective element that ensures the safety of payments on the Internet or in any other remote way (without the presence of the card and its owner during the payment).
A less well-known method of card payments is the so-called Mo / To (mail order / telephone order) - an order by mail or by phone (subscription to periodicals, etc.), which is not developed due to its insecurity (card details are sent by letter, by phone or fax).
The value of this code is used to verify the authenticity of the bank card. It is not present in the information on the magnetic stripe or in the chip, you will not see it on the receipt and it cannot be changed like a PIN code. This is secret information that cannot be read from the card, but it can only be transmitted by the cardholder himself (only during payment on the website). If the card data is stolen on the Internet (see security aspects below) or it is stolen, the attacker becomes aware of the card details, including its secret code, after which it will not be difficult for him to withdraw all your money. Fortunately, additional technologies have appeared, such as 3d-Secure, which significantly increases the security of online payments.
IMPORTANT! Do not confuse a PIN or card number (last digits) with a security code (card authentication code).
Each payment system has its own name for the secret security code.
American Express cards are rare, there are a number of international payment systems (for example, the Chinese UnionPay), but we will not consider them due to the fact that they are practically absent.
Other variations of the security code names: Credit Card ID (CCID), Card Verification Data (CVD), Card Verification Value Code (CVVC), Verification Code (V-Code, V Code), Card Code Verification (CCV).
If the security code is not on the card?
Not all cards have a code for verifying its authenticity. For example, it is not available on entry-level debit (payment) cards VISA Electron, Mastercard Cirrus Maestro, MasterCard Electronic.
They are not intended for payments on the Internet, but are used to withdraw cash from ATMs or to pay for goods and services at retail outlets. Although, for example, with the release of VISA Electron, the CVV2 code is still generated, although it is hidden on the card, and the possibility of payment on the Internet is determined by the bank that issued this card (check this possibility when registering the card).
On the other hand, you have the opportunity to pay with such cards only in those online stores that support the appropriate payment system (for example, Maestro) - they will accept payment without entering the CVV2 / CVC2 codes, but this option is very rare. Mostly classic, gold, platinum cards are accepted: Visa (Classic, Gold, Platinum) and MasterCard (Unembossed, Standard, Gold).
Where is the card security code
The three-digit code CVV2 / CVC2 (Visa / MasterCard) is located on the back of the card on a paper signature strip and is located after the card number, usually the last 4 digits of the number are indicated there (see the material on the appearance of a bank card for a more detailed study of the elements of your card). American Express cards already have four digits and are located on the front side on the right.
On a virtual card (issued virtually and used for safe, usually one-time payments, do not have a material medium) CVV2 or CVC2 can be recognized either by phone in the form of an SMS message or you will see it on the screen during registration.
Security aspects of online transactions
For the owner of a card (especially a credit card), security when making online payments on the Internet is important. The security code is one of the ways to ensure it, but it cannot protect against theft of money from the account.
The thing is that an attacker only needs to know the details of the card (they are all present on it) to gain access to the money. They can get them using the so-called social engineering (for example, phishing), when, under the guise of messages from official and well-known sites (portals, services), scammers massively send letters with a request to provide their passwords, logins, including credit card information ( sending to fake pages on the Internet), thereby playing on the elementary network and financial illiteracy of people.
Having given your data in this way, you can lose all your money on the account. Not only credit card data on the network can be stolen, but also cards from wallets and pockets. In this case, the security of your money will depend on how quickly your credit card is blocked.
With the development of financial technologies, network technologies are also developing. In particular, newer versions of Internet browsers have the ability to inform about a visit to a suspicious site (anti-phishing).
Payment systems, in turn, are actively introducing the new 3d-Secure technology (called: Verified by Visa for Visa, MasterCard Secure Code for MasterCard), which complements the standard methods of protecting card payments. Before each operation, a one-time password is generated and sent to the cell phone of the card holder (only to the number previously linked to the card, where, for example, SMS messages are sent when the SMS-informing service is connected), and payment will take place only after entering the sent password into the corresponding form.
This technology provides the highest level of security today, although it does not protect 100%, therefore it is recommended to choose banks with 3d-Secure support (by the way, according to the rules of international payment systems, each bank must have this technology implemented, which is not always done by banks).
