Take an extra method of payment with you.
Magnetic Strips stop working, wallets disappear or bank cards just get worn out from abuse! You don’t want to be stuck in a foreign country on the ultimate vacation without access to your funds. Always have a second card even if its a debit card where you can transfer funds via Online Banking or a Banking App. This is the card that stays in the hotel room safe with your extra cash, while you abuse your credit card.
