What is a card verification code CVV and how does it work?

Do you know what CVV is and why it is so important to know about it? To get more information about this, you have to read this post CVV completely and I hope you will learn a lot by reading it. Whenever you go shopping in a retail store, then you have to provide your credit card or debit card, but do you try to know what is written in that card. Like what is the CVV number, expiration date of the card etc. Often we extend these cards to make further payment. And swipe your front cards in the terminal and confirm your payment.

At the same time, when you use your credit card or debit card on internet or phone, then you will have to know about these three things to complete the transaction:

Your credit / debit card number
Card expiration date
CVV code, or security code
When a phone agent, mail catalog company or online checkout is asked about the security code, then they refer to the same CVV, or Card Verification Value or code. So today I thought why should you provide complete information about what is CVV Code or how to use CVV so that there is no doubt related to it in your mind. Then let's start without delay.

Do you know what CVV means? The full form of CVV ​​is Card Verification Value. This is a new authentication procedure that has been established by credit card companies, so that there can be at least fraud and prevent them during internet transactions. 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 on all major credit and debit cards.

This new feature is a three or four-digit code that provides a cryptographic check, for card information. So this CVV code is not a part of that card number, it is just a security check.

What is hacking
This CVV code provide 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. Every credit card company has its own name for the CVV code, but they do the same thing regardless of the card of any big company. For example - VISA calls its code as CVV2, while MasterCard introduces it as CVC2, and American Express makes it known as CID.

The back panel of Visa / MasterCard cards has a full 16-digit account number, after which it also has CVV / CVC code. Some banks only show the last four digits of your account number, behind which is the code. To prevent misuse of credit card, we need 3 or 4 digit code which remains behind the credit card. Whenever you save the information of your credit card or debit card, then your data is protected with a digital certificate which is certified by Secure Socket Layer (SSL) technology.

Where is the CVV Code in the card?
You must have come to know what the CVV Code is, but people often ask these questions, where is the CVV code found in the card. The simple answer to this is that this card is found in the rear or front panel. This code is a numeric code of 3 or 4 letters, which is given after your card number. It provides a lot of security where we do not need a physical card for the transaction. Here, the user should not only know their card number and expiration date but with that you would also know the CVV code to complete the transaction. This shows that the person providing the card is the real owner of the card.

CVV Code is not your PIN
People often get worried about the card's pin number and CVV code. Because both codes seem to be the same. But one thing to note here is that the CVV code does not have any contact with your PIN number. The PIN number is used to access your credit and debit card account in the ATM machine. Therefore, note that never enter your PIN number where you have been asked about the CVV code and do not enter your CVV code where you have been asked for the PIN number. Otherwise you may have to face inconveniences.
