When making a deposit at an online casino, you will need to have a credit or debit card that is supported by the casino. You will also need to provide the casino with your personal information so they can process the transaction.
You can find out whether your credit or debit card is supported by an online casino by checking the website of the casino. The website should tell you if their cards are accepted and how much they charge for using them.
Once you have decided which type of card you want to use and know what kind of fees are associated with it, simply click on that option when making an account at an online casino. Once there, follow all of the instructions provided by the casino until you're asked to enter your billing information. This will include both name and address as well as credit card number and expiration date—just like when making any other purchase online!
