What is the risk of giving cvv no on line paysites?

"I want to know the risk involved in giving this number on online site...."

If you have not installed latest virus protection for online transaction, there is likelyhood of any information catching/hacking program passing all the information so typed.

The same data can be used by the hacker to siphon off your balance.

There are various protection methods, but best is virtual cards.

Would you elaborate on virtual cards. Normally when on online , sites do ask your pin, and not cvv. I am having avast antivirus latest. But my question is why some sites insist on cvv number to process the transaction. It does not ask pin.  what is virtual cards?

All the bank provide virtual cards. For details, better google.

Oh, Thank you so much. So , net banking is a must to get the virtual card which would last only for the day or two. I will be careful. But my main question  is , why the sites are insisting that to process transacton.

That is double verification.

Hi, But that site did not ask for pin or there was no screen to furnish the pin. pl

CVV is final authetication for transfer of the requested amount from your credit/debit card.

No question of pin of the site.

CVV is an anti-fraud security feature to help verify that you are in possession of your credit card. For Visa/Mastercard, the three-digit CVV number is printed on the signature panel on the back of the card immediately after the card's account number.

Hi, Thanks for educating me on this . But some sites ask for pin, after furnishing the card number.. Is that safe to give the pin for those sites.

Any personal data or card pin, or bank details given to anyone, virtually or personally is UNSAFE.

Hi, Thank for information. But i do not remember the site. When i enter the bank details, and clicked next, it asked for the 4digit pin. Then the transaction was proceeded . I think different sites use different screens for processing. So, it is risk to give both and it is better to avoid online transaction altogether. To day i read in times of india, about how it is risk when so much methods, like phising, vishing , data chip in the machine slot would prove to be risky nowadays. Thanks for so much information. I do not use netbanking , so , i will be careful in future transactions. Even for cine ticket, all the details are asked to proceed. Some sites accept,some type of cards. strange are the ways of transactions. Thank you so much
