Money exchange in Nicaragua

I've found that Visa is much more commonly accepted than Mastercard. Check what network your debit card is on. Also, make sure it has a four digit pin, not a longer one. And bring a credit card, too, just in case. Sometimes true debit cards (the kind of ATM card that you can use in stores for cash purchases) don't work properly overseas.

Good point- Mastercard can be a issue in ATM's, as Visa rarely gets denied.
