If you do not already have one, you will have to talk with a representative of your bank. Typically, it is very easy to get a credit card for most people. As long as you have a good credit history, the bank will have no problem issuing you a card. If, however, you are rejected for any reason, then consider using a debit card. They function in the exact same manner, with the one difference being that you spend money that you actually own. There are players who prefer debit over credit cards for this reason alone.
