We have no doubt that one of the most important decisions that any new online casino games player has to make when they register with an online casino is how to fund their account. The question of which of our recommended online casinos to register with is generally down to the range of casino games they offer and individual preferences in that regard, but which deposit option to choose is equally important. All the online casinos on our list have a full range of deposit options but this month we want to focus on credit cards including of course the Visa card. Every online casino accessible in Ireland is a Visa casino, but just because this option is so widespread does not mean it is the best option for everybody. Many of us automatically reach for our Visa credit card when conducting business on the internet, and there is often good reason for doing so particularly with a new supplier, but the insurance element of using a credit card has no relevance when funding gambling on casino games. Quite apart from the rights and wrongs of gambling with what is effectively borrowed money, using a credit card as an online casino deposit option will almost certainly cost you money. The bank will probably apply a surcharge of up to 2% on any transaction involving gambling, and because it is a cash transaction on a par with taking money from a cash machine there will also be interest charged from day one. These two additional costs mean that you start every new session of playing your favourite casino games showing a loss. If you really must use a Visa credit card to fund your online casino games, at least consider opening an e-wallet account such as Pay Pal or Neteller and using that account to fund your online gambling, Even if you fund your e-wallet with your Visa card the bank will not know what you are doing with the money and there will be no surcharge.
