CVV means Card Verification Value, it is a number that is often written on the back of the card. This number is very important to complete online transactions. Also, they should never be shared with anyone.
This is a new authentication procedure that has been established by credit card companies so that there is minimum fraud during internet transactions and they can be stopped.
For this, the card holder has to enter the CVV number during the transaction time to verify his card. This CVV code is a security feature that is used for “card not present” transactions (such as Internet transactions), and is currently available in almost all major credit and debit cards.
This new feature is a three or four-digit code that provides a cryptographic check, for the information of the card. Therefore this CVV code is not a part of that card number, it is just a security check.
This CVV code gives us correct information about the actual card holder. This shows that the customer who is placing the order is the real owner of the card and he is using the card account properly.
Each credit card company has its own name for the CVV code, but they do the same thing, whether they are cards of any big company. For example – VISA refers to its code as CVV2, while MasterCard refers to it as CVC2, and American Express refers to it as CID.
A full 16-digit account number resides in the back panel of Visa/MasterCard cards, followed by the CVV/CVC code. Some banks show only the last four digits of your account number, behind which the code remains.
How CVV Protects You From Being Fraud?
The main purpose of Debit and Credit cards is payment processing in online transactions and other virtual payment gateways. These portals do not have permission to save your information such as card number, CVV number as it is against their Per Payment Card Industry Data Security Standards.
So even if your vendor has all the details of your card, but still they cannot access your CVV number. This makes it impossible for your card to be misused.
Therefore, if ever there is an attack on the data security company that issues credit card or debit card, then since your CVV’s number is not stored in their databases, even if your credit card information is leaked, it is the CVV. If not, the transaction cannot be completed.
What are the Drawbacks of CVV?
The only drawback of this is that if ever the credit card is completely duplicated in which its magnetic stripe is also present, then fraudsters can also access your card’s CVV code and misuse it. .
