What’s the best payment system to use for international transactions?
Answer by Faisal Khan:
Although various payment systems will process oversea card payments, one the best experience I have had in this regard is 2CheckOut (www.2checkout.com). The only downside it that they are expensive. This, I am assuming you want to "receive" payments via credit cards.
Paypal has a large coverage map, however, it still has a very restricted market, outside of the US, of users who can pay out (versus receiving money).
Depending where you are, China's Unionpay is also a great option to look at.
If you transaction volume hold weight, you might want to check with the merchant services offered by HSBC.
