Facebook credits apps

Hello, how i can rewards my visitors with facebook credits?
where buy it? how develop an application, etc

 

You'll find lots of good information here:

http://www.facebook.com/credits/

 

Edit: I just read the Facebook Credit forums and it looks like that Facebook let's only a few companies buy Facebook credits and give them to their users. So I guess it's impossible to achieve what you're trying, at least for now... :/
