The things to look for are where you can deposit and withdraw, and what fees they charge.
The one important thing to remember with credit cards is to pay off your balance in full each month before the due date, so only use it to buy things that you would be able to with your own cash and bank funds.
Any interest you pay wipes out almost any other perk you get from credit cards like cash back or whatever (the exception is fraud/scam protection). If you want I can explain how interest works for most cards in North America.
