Android Market CC question

[androidb]

Hi Guys,
I have a question about the Android Market. I bought an app for my friend on his phone using my credit card. It looks as if my credit card is now stored on his phone. Is there any way I can get rid of this? Is my credit card now associated with his Gmail account? I logged into checkout.google.com with my account and it does not show the purchase....which makes me think my card is now associated with his account.

I would of thought it would just be a matter of removing your credit card from his google checkout account and then just put it back on your own account.

I just looked on my account and there is an option to edit your payment method so it should be possible.
