Before your next international trip, make sure to back up your documents.  Just in case.  Having a copy of your passport is the most obvious necessity; if you lose it, you lose your proof of entry. In some countries, that can be a huge roadblock to getting help. Scan and print a copy of your passport, or digitally save the images somewhere secure that you’ll have access to while you’re on the road.  Other documents that should be backed up include proof of travel insurance, health insurance, any relevant visas, and student or teacher IDs are crucial. It’s also a good idea to keep your credit card and banking information handy–and, of course, as secure and inconspicuous as possible.  Keep a hard copy of some of this information somewhere organized and accessible, in the off chance that you’ll need it.
