Credit cards have long been the primary funding method that is available through various online gambling sites, but the credit cards capable of being used have somewhat shrunk over the course of the years. This has been somewhat limited for some players, specifically those who do not have a VISA card for their casino deposit methods.
Unfortunately the use of MasterCard has shrunk, and has even been removed from the cashier of some gambling sites. All across the board, in poker rooms, casinos and sportsbooks alike, the number of different gambling sites using MasterCard has been somewhat smaller.
Even some of the largest gambling sites have stopped using MasterCard. While this has not made it impossible for players to deposit, those who use this card will find it slightly more difficult to actually make a deposit without too much difficulty.
While MasterCard is not the first credit card to stop being useful through some online gambling sites (See: American Express), it is definitely a big hit tot he simplicity of the Internet. With the lack of easy funding methods, especially with e-wallets, it is becoming even more necessary to find a versatile and easy funding method.
