Almost every credit card transaction in India goes through this kind of system. At a POS terminal you need to enter a pin (same thing in Europe). For e-commerce you need to enter a password after you enter all your CC details. It's called Verified by Visa or Mastercard Securecode, depending on what card you have. The downside is that apparently the user agreement states that if your password gets stolen (as well as your credit card details) then all liability is on you.
