I'm currently planning to integrate a donation system into a web page for a project that I manage. Currently, there are two services I'm looking at using - PayPal and Amazon Honor System.
I want the system to be as easy-to-use - basically, if people choose to donate, I'd like them to have to do so in as few steps as possible and in a manner that is extremely clear (as in there aren't convoluted steps or form fields to fill out).
Does anyone have a recommendation on which service is better to use, and why said service is better than the other?
