Post your vIew. This is really a Good Habit to Work Online with Card.
I shop online. My credit card has a low limit, so I'm not too worried about fraud. My bank has always been very helpful in situations like that, and they've helped my mother and uncle out when they had their cards compromised and fraudulent purchases made. Not like I have much to lose in my checking account anyway. =p
I mostly use it for game purchases via Steam, or computer hardware on Newegg. Come to think of it, those are the only places I can think of that I've used my card online in the past year.
Of course, that being said, you have to be careful where you put that card information out there on the Internet. It could very easily end up in the wrong hands.
