This information is recovered when the card is swiped through a magnetic reader machine. This security number is one of the many advantages of a debit card. CVV is to debit card what a security guard is to an establishment.
It helps safeguard your debit card against theft, fraud or unauthorised transactions. The CVV ensures that only the card owner uses the card. Even if someone gets hold of the debit card number , they cannot transact without the CVV. Whereas the CVV is used when making payments online or over the phone.
Fortunately, unlike other details of a card, the CVV cannot be stored while swiping or while punching online. Even though the CVV provides security, it does not absolve users of the caution they should take while using a debit card like not sharing the CVV with others. We hope this article has been informative with respect to the nuances of a debit card. It is a three-digit card security code meant for security purpose of debit and credit cards while making financial transactions.
CVV Number is used to provide enhanced protection to the users of debit and credit card against any fraud or theft. CVV Number is the last 3 digits of the number which is located at the back of credit and debit cards. Those 3 digits are the card security code which is different for every user.
PIN Numbers are used to withdraw money from an ATM using debit cards or while buying products in person using your debit card. It is also used while taking a cash advance using credit cards. As a matter of security, no two cards have the same CVV. Even if your credit card number is exactly the same, you will still have a different CVV. As it turns out, CVVs are not random three- or four-digit numbers. Rather, banks generate them using four pieces of information: primary account number, four-digit expiration date, a pair of DES Data Encryption Standard keys and a three-digit service code.
For obvious reasons, the precise algorithms used are unknown. To avoid becoming a victim of credit card fraud, you should protect your CVV like any other important piece of financial information.
Here are seven simple ways to prevent your CVV from falling into the wrong hands. Banks and merchants stepped up security for in-person transactions with the introduction of chip-based debit and credit cards.
This technology enables the internal code to change each time the card is read, a vast improvement on the magnetic strip. Not surprisingly, this has been very effective at reducing fraudulent activity.
But what about CNP card-not-present transactions, such as those taking place online or over the phone? Clearly a physical chip will not be helpful; this is why there is a CVV printed on your card. However, the most skilled criminals are sometimes able to access CVVs, even though merchants are prohibited from digitally storing them. This would happen on a miniature lithium battery-powered screen on the back of the card. Selecting the frequency of the code change has its difficulties, and the cards would likely be four to five times more expensive to produce than current models.
That said, the fraud savings could more than make up for the increased production costs. Accordingly, other methods of generating dynamic CVVs have been developed, but none have seen widespread implementation yet.
