MasterCard or Visa are casino deposit methods at some casinos. If your card is a debit card, you are limited to the available balance in you bank account. If the credit card is a regular card then your card limit will come into play when you make a deposit to your casino account. Many casinos are using non-descriptive names when the charge comes through on your statement. This is done to make it less obvious that the card is being used in a gaming establishment. US players have a very real problem with some casinos using their credit cards to make deposits to their casino account.
