In addition to online gambling institutions, the US government also offers support for a number of online bank transfers made from one US gaming site to another. Although not all online gambling sites are required to transfer funds between casinos, many do, as a means of ensuring that their clients will be able to continue at this website at any of their sites after a transfer has been made. For example, the online bank transfers between online casinos MasterCard and Visa are done as a means of ensuring that players can continue playing after a transfer has been made. In many cases, players who use a credit card to make their online casino deposits will receive an email asking them to confirm their initial card with their bank in order to receive the deposit amounts. In other cases, the online casino software will prompt the player to enter a banking account number and other personal information in order to process the online bank transfers.
