How to pay online safely

I had to get a domain name for my one of other blog, ( So in order to pay for domain I wanted to find a safe paying method. I had a visa debit card but I think I should go for visa virtual card which contain certain limit of credit. Using virtual credit card is very safe because when you paying using it suppose hacker got your number. But he can only grab the small amount of money which is in your virtual credit card.

So I went to Sampath Bank (I am a Sri Lankan, and Sampath is very outstanding bank is Sri Lanka) and buy a 2500 LKR virtual credit card. (equal to 24 USD). I pay handsomely to google checkouts and buy my domain name.
