Your overseas customers can proceed to payment through SwiF using credit cards, Visa or Mastercard.
When they purchase your product or service, amounts payable will be displayed in Malaysia Ringgit. Once they proceed to payment their bank will convert the amount to their currency based on the current transaction rate.
If you are embedding SwiFLink to your website, you can always add a plugin that will automatically convert the currency for your customers. This serves to give your customers an indication of purchasing price in their currency.
