Cards, Fees & Fraud Controls
Card-first places, backup cards, foreign fees, fraud freezes, and the payment stack that survives one failure.
One card is not a system
Carry a primary card, a backup card, and a way to access cash. Different networks and issuers are safer.
Fee-free is only part of the story
Foreign transaction fees, ATM fees, cash advance rules, and dynamic conversion all change the real cost.
Fraud controls should be reachable
Know how to freeze, unfreeze, message support, and authenticate without the lost card or lost phone.
Use debit carefully
Debit cards are for ATMs. Credit cards are usually cleaner for purchases because disputes and exposure differ.
