What is activated adwords account?

I have just got 50$ (2500 INR coupon ) from the google. Its of no use for me. I want to know can I make activated adwrods account using it?

Please let me know more about it.

That is you have to activate your account with a credit card and then you can use your coupon to use that $50. They will atfirst deduct $5 from your credit card to verify your account.
