Yes, you can - http://en.wikipedia.org/wiki/3-D_Secure

When I buy something online using my CC, and if the payment processor supports that (mostly local/european shops), I get redirected to a page on my bank for verification. Some banks require the PIN to be entered, some others to enter your login credentials, some coordinates from your code card or even verify with a SMS code.

Not exactly using the chip, but it involves the PIN surely.

If the payment gateway decides to not implement this kind of protection, the payment goes through anyway (I'm guessing it'll be more expensive for the merchant, but still).

My bank issues chip and PIN readers for login and signing purposes. They are also used for 3-D Secure transactions.

MasterCard has the same thing in the US. I think it's called SecureCode.
