Credit cards issued by most financial institutions such as banks are usually made of plastic. However, there are those made of metals, including steel, titanium, and gold.
Such cards are traditionally for VIP clients and come with additional benefits and costs. Some financial institutions offer virtual credit cards, usually for clients who intend to use the credit cards for online transactions only.
Nearly all mobile casinos offer credit cards as a payment method. That is usually in a bid to capture even more clients, given that credit cards are among the most secure and popular payment methods of making transactions.
The benefits of credit cards usually rely quite a lot on the policies of the issuing financial institution. The benefits can be extremely favorable to mobile casino players, which is why most people use them.
