Are Credit Cards Accepted?
There are still prohibitions against using US-issued Visas and Mastercards. Make sure you bring cash to spend. Keep in mind that some businesses, especially those in rural areas, only accept cash.
If you choose to use a debit card abroad, check with your bank to learn how much of a fee they will charge for an overseas withdrawal. The fee for withdrawing money from the ATM will probably be higher in Cuba than it is at home. Withdrawing money from an American bank is especially expensive, and comes with a whopping 10 percent fee.
