 What does a CVV represent?

The CVV stands for "card verification value." It is a three- or four-letter number found on most debit and credit cards.

There are several other acronyms for this defensive feature within the industry.

The purpose of CVVs
As chip-enabled card technology has been able to significantly reduce portable card fraud, criminals have shifted their focus to digital. Creating fraudulent cards has opened the way for online information theft. Attach a CVV, which is used by banks and credit card manufacturers to reduce fraudulent digital transactions.

There are two CVVs associated with most debit or credit cards. The first is coded in a magnetic field used for personal transactions; the second appears on the card. This is what you should include when shopping online.

Although it may be easier compared to skilled hackers to access credit card numbers and expiration dates, CVVs are far more difficult to track. This is largely due to industry regulations. According to PCI (Payment Card Industry) standards, merchants may keep your credit card number and expiration date, but they cannot keep your CVV. So, while you may not want to enter the number of each online purchase, doing so provides that extra layer of security.

Where do I get a CVV?

Getting your CVV depends on the type of card you have. On Visa, Mastercard and Discover cards, you will find a three-digit code on the back, usually within or just above the signature line. American Express does things differently, placing a four-digit CVV at the front, above the Amex logo.

Is There a Difference Between CVV and PIN?

User-created PIN "ID number". Most PINs are usually four-digit, although some banks require longer numbers. Credit cards use PINs to make payments, while debit cards are used to withdraw cash or start purchases. None of these PINs match CVV.

CVVs are automatically generated by the credit card issuer and printed on the card. Although the bank may initially provide you with a PIN when your debit or credit card is issued, it is only temporary. In most cases you will need to change it to a designated number. You do not have such control over CVV.

Does the New Card Have a New CVV?

 
In terms of security, no two cards have the same CVV. If you sign up for a new credit card or replace an existing one, you will end up with a new code; the same applies if your current card expires and you get a replacement. Even if your credit card number is exactly the same, you will still have a different CVV.

How Are CVVs Produced?

 
As it turns out, CVVs are not three- or four-digit random numbers. Instead, banks produce them using four pieces of information: a primary account number, a four-digit expiration date, two DES (Data Encryption Standard) keys and a three-digit service code. For obvious reasons, the exact algorithms used are unknown.

How Can I Protect My CVV?

To avoid being a victim of credit card fraud, you should protect your CVV just like any other important financial information. Here are seven easy ways to keep your CVV from getting into the wrong hands.

Install anti-virus software on your computer. This will scan for viruses, keyboard access software and other tools that cybercriminals use to steal personal information.
Password-Protect your home WiFi network. If not, anyone within range can connect, monitor your internet traffic and track any information you submit.

Only enter your credit card details into trusted websites. Avoid websites that do not have “https:” address; same for those who do not display an SSL lock in your browser window.
Use a VPN when browsing away from home. While this may be very difficult at home, when traveling or using public WiFi you should use VPN software to protect your personal information.
Do not share photos of your credit card, either with friends or on social media. Someone can make an unauthorized purchase using your card data.

Ignore unsolicited requests for personal information. If someone asks for your credit card information over the phone or email, ask why they need it. If sensitive financial information needs to be transferred this way, it is usually best if you are the first to contact.
Check your account activity regularly. Review what you did online or when the statement came by mail to make sure you authorized each one. If there is a charge you do not know, contact your bank immediately. You may need a new card.

EMV Chip Cards and Dynamic CVV
Banks and retailers have strengthened the security of personal transactions by introducing chip-based debit cards and credit cards. This technology allows internal code to change each time a card is read, a significant improvement in the magnetic field. Not surprisingly, this has been very effective in reducing fraudulent activities.

But what about CNP (non-card) activities, such as those done online or over the phone? Obviously a physical chip will not be helpful; that's why there is a CVV printed on your card. However, the most talented criminals sometimes have access to CVVs, even though marketers are prohibited from keeping them digitally.

The proposed solution to this problem is called “dynamic CVV,” as it will allow the printed code to change within a specified time. This will happen on a small lithium battery screen on the back of the card. This may seem like a guaranteed success, but although the technology has obvious advantages, it is not perfect. Choosing the frequency of code switching has its difficulties, and cards can cost four to five times as much to produce than current models. Having said that, the savings of fraud is more than closing
