International Travel
You might be a frequent international traveler or someone fond of shopping from international websites; in either of the scenarios, transactions in foreign currency have to be done, and as you know, almost all credit cards charge a markup fee on foreign currency transactions. The general market standard for mark-up fee is 3.5% of the transaction amount.
However, some credit cards offer a lower foreign currency mark-up fee so that users are able to transact in a foreign currency without worrying much about any overhead charges. Usually, these cards are either travel credit cards or top-end premium cards. For example, the forex mark-up fee applicable for HDFC Infinia Credit Card is just 2% of the transaction amount (instead of the usual 3.5%). Then there are other credit cards that, although they charge the same mark-up fee on foreign currency transactions, compensate for the same by offering a higher reward rate on transactions made in foreign currencies.
