One of the most important decisions you will be asked to make when you register with an online casino is how you intend to fund your stakes when playing casino games. All the major online casinos offer a wide range of deposit options including debit cards, credit cards and e-wallets, and for those of us who live in Ireland Paddy Power and Ladbrokes will even allow us to use cash at their high street shops. Using a credit card for internet transactions often has many advantages over other methods of payment for goods and services, and has understandably become the favourite option for many people, but is it the best deposit option when playing casino games online. Probably the biggest credit card company is Visa, and it is no surprise that all the main online casinos are Visa casinos and will happily accept this method of depositing money into your casino games account, but using a credit card for this purpose should in our opinion carry a financial health warning. Perhaps it is not for us to comment on the moral question as to whether it is acceptable to use borrowed money for gambling, and if you are smart enough to pay off the whole balance every month this is not an issue, but what about the bank charges you will inevitably incur by using a credit card. Most casino games you will find on the online casino sites have a house edge of some sort and any additional costs you incur simply to make money available to fund your stakes will further reduce your chances of winning. Using a Visa credit card for gambling often results in an automatic 2% charge from the banks, on top of which the transaction is in their eyes the equivalent of withdrawing cash from a cash machine, and therefore attracts interest from day one so that even if you do pay off the whole balance at the end of the month you will still be paying interest. Clearly it is none of our business how you fund your casino games, but we believe it is right for us to point out the drawbacks and perhaps recommend that if you want to use a credit card, use it to fund an e-wallet and use that to make your online casino deposits.
