Tamarindo has 3 banks that exchange currencies.
BAC San Jose usually has the shortest wait.
Banco National and BCR are the national banks and usually have a line up.
There is also a Scotia Bank at the Auto Mercado just outside of town.
Most of Tamarindo businesses accept US Dollars but will usually charge an exchange rate and give change in the local currency of Colones.
BAC (Banco de San Jose) has the ATM's that seem to accept the most types of credit, debit and bank cards. Cash can be withdrawn in US Dollars and Costa Rican Colones. Limit per withdrawal is 300,000 Colones.
The cash machines at Banco National and BCR do not accept all cards and their limit is only 100,000 Colones per withdrawl.
