Electronic Payment
Good exchange rates may be obtained by making purchases with a credit card. Cards commonly accepted in the U.S. are Visa, MasterCard and American Express. Some stores and restaurants in Charlottesville also accept Apple Pay.

We recommended that you have some cash on hand when you travel for tipping transportation personnel ($1 and $5 bills are best). Airport exchange rates may be on the high side. Better exchange rates may be available by exchanging currency before you travel or by ordering cash online. Currency also may be exchanged at banks in Charlottesville which are usually open from 9:00am to 5:00 pm, Monday through Friday, except on national holidays. A few banks are open 9:00 am to 12:00 pm on Saturdays.
