Security

I have two questions:

 

1)How can I set up IE9 to prompt me every time someone wants my location rather than an all or nothing situation?

 

2)My credit cards have been hacked twice in the last year from online buying.  I have heard of one time or limited credit cards.

 

The reason i am posting in a Norton site is that someone told me NIS can be custom configured to block location requests.  I know there is a Norton safe, but dont think that can prevent hacking a card, right?

 

thank you
