There are ways to do this, if you want to.You can activate the 3D Secure system, the official MasterCard casino verification system that sends you a text message on your phone each time you make a payment with an additional verification code. In the same vein, if you sign up for a MasterCard casino fast payout system you will enter your card details only once and not upon every transaction. The info will be safely stored on the official MasterCard servers.
