Can someone use my credit card online if he/she only knew the card number, the security code (3 digits), and the expiration date? do he/she need any other information to use my credit card online?
So many cards are lost / stolen that MOST on-line retailers will ONLY ship to the card holders address .. (although you can often get that changed by going into 'modify order' after the card has been accepted)
So the quick answer is 'no' = if they don't have your address they can't place the order in the first place ..
NB> if you have any reason to believe that you card details have been copied / stolen RING THE "LOST OR STOLEN" card 'hot-line' NOW (the longer you leave it, the more likley the thief will find some-way to take money off the card )
no, they would need the long 16 digit code on the front too...
however, if they were logged onto your personal computer where you have saved card details on regularly used sites then perhaps.
if it is a visa card i recommend the verified by visa application for added security 
That is often all they need. Companies usually only ask for extra info if you are buying something very expensive.
If you think your card is being,or may be misused call your card company to cancel it immediately.
They'd also probably have to know the name and billing address associated with your card. I'm pretty sure every site I've ever shopped at has required that information.
They would need to know all digits and the home address associated with the account.

Add another input form, 'Was your Credit Card compromised? Put your number and security code in the boxes below to check!'. Then if anyone tries to type in the form, a popup that says "What have we learned?"
Apparently they have a much more "open" system that anyone can work with.. Literally anyone... including those who want your personal info and credit card details.

It''s asking for the security code which is a 3-digit number on the back near or on the signature strip. Unless it's an American Express, then it's the 4 digits on the front face of the card near the top right corner, not beveled out, but just printed in black ink.
System Announcement Today's Security Code is: 30, 64, 8, 82, 0, 5.
Either there's a image security code or it's talking about the security code on the back of the card (usually 3 to 4 digits)
I know you said don't go there. but make sure the 3 to 4 digit pin is included on the info.
