Check web sites. Many providers will mention on their sites if they take cc. The school of though on cc, is it leaves a paper trail, never a good thing.

I accept electronic payment by way of amazon or other gift card that can be sent directly via email
The problem with CC is people can deny the charges and rip off the provider after the fact

P4P has enough risks without leaving an easy-to-follow paper and electronic trail. And of course this means a stranger having a piece of paper with your full name and signature.  Just a word to the wise.

If you use agencies, I think they will take them.  Been a long while since I used them though so this may have changed.

a money pack is probably the most safe way to go other than cash.  But you need the cash to get the money pack.  So if you have the cash available why not use it?  

If you want to use a CC because you want to finance the cost of the visit, then you must be REALLY horny. If that's the case I would suggest a visit to Rosy Palm and Her Five Friends supplemented with a copy of Playboy until your finances improve.

If you "found" someone else's CC and are trying to use that then shame on you.
