Elavon for direct card (they supported 3DSecure early back in the day), PayPal, and Bitcoin. We used to support Western Union, but we got blocked after a random amount of funds was received, their support was not able to help. Business is for digital goods. Would like to support worldwide bank transfers if it can be safe and quick for both sender and receiver, anyone got any tips?
