You may only use Visa and MasterCard credit cards. However, please check with the respective banks to ensure that you are allowed to make online purchases using your credit cards.
Some credit cards are 3D Secured. This means that before confirming your online purchase, you will be asked for a personal password or details for verification purposes that you are the owner of the card. Take note this feature applies to certain banks only. Please check with your bank first to find out if your credit card is 3D Secured.
