Charity made hard

If you log into wikipedia lately you get this huge message from Jimmy Wales himself asking for money (strangely enough just read somewhere that they have a new board of directors and a new chairwoman with nothing better to do than spend about 6 mil euros they have already raised). Anyway, what I am mainly concerned with here is that even if I wanted to make a donation, I would have to go through a lot of trouble.
Romanians do not have a charitable streak - obviously, we have been without money for such a long time we do not have the drive to give it our freely. But even with new stuff opening our eyes and with truly emotional causes coming up, it's really effing hard to make a donation. Online, it's basically impossible unless you want to go through the hassle of being rejected time and time again by PayPal because you live in a country with an awful record.
So, my question is this: why can't there be an integrated donation system. Basically like PayPal makes your purchases possible, this system would make a summary of all existing causes and donation requests and you only needed to log-in, make an account, register a card and donate whenever and wherever you felt like.
I want to give, really, but I don't want to try really hard to give.

PS: if there is such a thing, direct me to it. Jimmy needs my help.
