I've been doing the credit card thingie for nearly two years now and can vouch for the safety and security of donating that way. And I had no trouble at all switching over to the new system.

I've had no problem with the credit card donations except for one thing. Several months ago I cancelled the credit card that I was using for my (very modest) monthly donation and no one from FR notified me that my donations had stopped.
I hope that has changed because I felt terrible about it when I found out.
As far as security goes, donating to FR via credit card is as secure as any transaction on the internet which is probably more secure than using a credit card at a store and leaving a paper trail.
