There are two components to the CVV. The first code is recorded by the card issuer in a magnetic stripe. The long black stripe at the back of your Debit Card contains a large amount of data. The code is recovered by sliding the card through a magnetic stripe reader that reads your data to establish your unique identity.
When properly used, the CVV is highly effective against some forms of fraud. For example, if the data in the magnetic stripe is changed, a stripe reader will indicate a "damaged card" error. The flat-printed CVV is (or should be) routinely required for telephone or Internet-based purchases because it implies that the person placing the order has physical possession of the card. Some merchants check the flat-printed CVV even when transactions are conducted in person.
Why not to Share “CVV” and other Card details
CVV is used when you make any on line payment.
While making online payment you need to enter 16 Digit card number, Card Validity Date and CVV.
Never Share your card details to anyone.
Your card details can be used to make online payment/purchases without your knowledge
