It sometimes seems that credit cards have been around forever and indeed it is some 60 years since the first Diners Club card appeared in America but even this was not a true credit card as the balance had to be paid off every month. The two main credit cards of today which can be used to make online credit card casino deposits are Visa and MasterCard although some online casinos will accept other cards. In Ireland the original Visa card was Barclaycard but today there is a great variety of bank credit cards for online casino games use. Visa is of course also a debit card and funding your online casino account with a debit card is more economical than funding your online casino with a credit card. The difference being that a debit card is an instant transaction and the money needs to be in your account before it will work so the money will appear immediately in your casino account and the online casino will get paid immediately. Using a credit card for your casino account is however not an instant transaction despite the fact that the money will be instantly available in your casino account; the online casino does not get the money immediately and for this reason will often make a charge for the transaction. In addition the bank that issues your credit card will also make a charge for depositing into an online casino and they will make a separate charge for interest from the day of the transaction. If you have the choice therefore, do not deposit with a credit card.
