Read the pricing table
Before applying, find the annual fee, the fee for purchases (foreign transaction fee), the cash advance fee, the late fee and the balance transfer fee in the card's disclosure table.
Automate the minimum payment
A late fee is triggered by missing the minimum. An automatic minimum payment, topped up manually, removes that risk.
Leave over-limit coverage off
Under Regulation Z, an issuer can't charge an over-limit fee unless you have opted in.
Match the card to the job
Use a card without a foreign transaction fee for travel and overseas merchants, and avoid credit card cash advances.
