As more and more of us purchase goods and services over the internet from our personal computers or our mobile, we have become used to paying for those transactions with a credit card. There are of course good reasons to use a credit card for some online transactions, particularly where there is a possibility that the goods or services we are buying may prove to be unsatisfactory and we may need the insurance element of a credit card to ensure redress. There is a danger however that using a credit card for all internet payments becomes a habit, even when it is not necessary or indeed advisable. One prime example of an internet transaction which should prompt second thoughts on this type of payment is making deposits into an online casino account. One of the biggest credit card supplier is Visa, and almost all the online casinos are Visa casinos which willingly accept a Visa credit card as a deposit option for playing casino games online, but is it the best deposit option for us. Quite apart from the obvious doubts we should all have about gambling with borrowed money, even if we always pay the outstanding balance every month, using a credit card has other important disadvantages to consider. In spite of repeated warnings on this subject, we still hear of new online casino games players who are unaware that for reasons best known to themselves most of the banks which issue Visa credit cards invariably apply an additional surcharge on any transactions involving gambling, often as much as 2% of the transaction value. Then there is the fact that an online casino deposit is considered to be a cash withdrawal which therefore incurs interest from day one, so that even if you settle the balance in full every month it will still cost you additional money on top of the surcharge. All in all using a credit card to fund playing casino games at an online casino means that we have lost money before we even place a bet. There may be good reasons why a credit card is the best online casino deposit option for you, but be aware of the additional costs involved.
