As part of Chile, the currency used is the Chilean peso. However, US dollars are very welcome, as are Traveler's Checks. You may need to show your passport to cash the latter.

Some places take credit cards, but, as it can take months for proprietors to recover the money, it the least welcome form of payment (and some will even offer a cash discount over credit card purchases). Few islanders will take French francs.

Money exchange for all important currencies can now handled at the island's bank.

Tipping on the island depends upon where you are staying. If you are at one of the better hotels and have received good service, you may wish to leave a tip for the person who cleans your room and brings fresh towels, etc. It service is not good, forget it. If you are staying at a small residenciale, tips are not expected.

There are several restaurants in town, and, at the more upscale ones, a tip might be expected (15%). The small places which are usually run by one person (the owner) are less likely to expect a tip, but, if you have a waiter or waitress serving you, a tip is very much appreciated. The difference here is whether or not you are dealing with an owner or a paid employee.

Some tourists who hire a guide to take them around the island may tip the guide if they have had a particularly good experience.
