A foreign transaction fee may be charged by your bank if you make a payment in a foreign currency or make a purchase online from an overseas merchant. For example, a Singapore online merchant displayed prices in US Dollars and customers paid with a credit card issued in the United States. A fee is charged as the transaction is considered to be processed outside of the country.
The foreign transaction fee charged by the bank for processing payments cannot be controlled by Gametize or Gametize's payment gateway, Stripe. You will have to contact your Banks or card issuers directly if you would like to know more with regard to the foreign transaction fee.
