I am planning to have an online business targeting South Korea.
It seems that most Korean payment gateways only support Internet Explorer and Windows. It is severely limited for other browser and platform users to access to most Korean commercial websites. But I would like to support to all users.
I found a couple of cross-browser/platform Korean payment gateways, but they are more expensive than others. (fee for each transaction 3.5-3.8%, while regular payment gateways pay around 3.1-3.4%)
Would there be a solution for this? Would there be a better way to use a foreign payment gateway?
