Forex Card vs Credit Card Abroad: Which Should You Use?
A prepaid forex card and a regular credit card can both be swiped abroad, but the cost structure behind each is very different — and picking the wrong one for a given purchase can quietly add up over a trip.
How a forex card works
A forex card is loaded with foreign currency at a locked-in exchange rate before you travel. Because the currency is already converted, you are protected from rate swings during your trip and there is no foreign transaction markup on each swipe.
How a credit card works abroad
A credit card converts each transaction at the prevailing rate on the day it is processed, and most cards add a foreign transaction fee of 2-3.5% on top of that. Cash withdrawals on a credit card abroad also usually trigger a cash advance fee and interest from day one.
A simple rule of thumb
Use a forex card for planned spending — accommodation, shopping, dining — since the rate is already locked in and there is no markup. Keep a credit card as a backup for large or unplanned purchases, since it is easier to dispute charges and some cards offer travel insurance or rewards.
Do not rely on just one
The safest approach is carrying both: a loaded forex card as your primary spending method and a credit card as a backup in case a card is lost, blocked, or not accepted somewhere.
