To make online payments safer, the Reserve Bank of India has made it mandatory, for all online transactions to have an additional level of authentication from August 1, 2009 onwards. For Visa/MasterCard credit/debit cards, the additional level of security is a password that you will have to enter after providing your credit/debit card details while making online recharges through Tata Sky.
You need to register with your issuing bank (i.e. ICICI Bank, HDFC Bank, SBI, HSBC etc) to obtain the Verified By Visa (VBV)/MasterCard SecureCode (MSC) password. If you are not registered with the issuing bank, then your Visa/MasterCard may be declined while making a payment through Tata Sky, from
August 1, 2009.
What is "Verified by VISA"/"MasterCard SecureCode" password?

VBV/MSC is a service that will let you create/use a personal password with your credit/debit card, giving you added assurance that only you can use your card to make purchases over the Internet.

It provides added assurance by authenticating the cardholder while using the Visa/MasterCard to make purchases online.
