I recently wrote about which card issuers give the best exchange rate for foreign transactions. And ran an experiment which showed MasterCard had the most favorable rates.
But that might not be the case in every situation. Deciding which credit card to use when traveling abroad can be tricky, because the major banks use a different conversion tool for rates.
The Mercez app can check which card gives you the best exchange rate from the local currency into US dollars when making your purchase.
I’ve been playing with the app and the concept is great, but it’s not perfect. Here’s my full review.
