Despite the many advantages of using MasterCard, there are a few drawbacks. For one, the fees can be relatively high. Credit and debit cards are subject to transaction fees, often totalling between 2 and 3 percent of the total transaction. Moreover, transfers take time, usually 1-3 working days, making transactions less instantaneous than some alternative methods.
In addition, there are countries that are not eligible for MasterCard payments. Players should check the terms and conditions of the website they wish to use as some countries may not be supported. Finally, the fact that fees apply and the currency exchange rate could also be disadvantageous for those on a budget.
