Citizens of the U.S., Canada may enter Costa Rica without VISA but they now require a valid passport.  Tourist cards are no longer accepted as a travel document and have been discontinued. Citizens of all other countries require also a valid passport to enter Costa Rica. You are required to carry your passport with you at all times. If by any chance I.D. is required by officials during your stay, usually a photocopy of your passport showing your photo, passport number and entry stamp will usually suffice.
