Credit and debit cards are accepted widely, but cash remains king, so it's best to keep a bit on hand, preferably in smaller bills, as many vendors can't or won't make change for large bills (50 and 20 peso notes are ideal). If using a credit or debit card, notify your bank or card company prior to traveling; they will put a “travel alert” on your card, preventing it from being flagged for fraud.
