If an affiliate lives in the U.S., PayPal is the best, safe and quickest choice.
If an affiliate lives outside the U.S., PayPal may be available in some countries. In that case, it is a good choice. If not, the card offered at TripleClicks is an excellent choice. Another good choice is TCurrency if an ECA in the country of residence offers them. BidCoin is also another good choice if that is offered by ECAs in the country of residence as well.
