• Rule #1 Scan into a PDF file, every document you do not want to lose and no matter you think it is important or not. How to scan and save?

• Print every critical document to keep near and safe such as a color copy of your passport.

• Passport Scan and print a couple color copies of your passport. Keep a printed copy in your wallet or purse. Lock your real passport in the hotel safe. In France, you must carry an ID card at all times. Police will accept a printed copy but offer to fetch the real-deal at the hotel. Police will not bother you if you are polite and respectful. Remember that a US driver's license is not a legal ID card outside the US
