These items are most secure when they are locked in a hotel safe. If you wish to carry them with you,conceal them in several places rather than putting them all in one wallet or pouch. Avoid using funny packs,handbags,and outside pockets. One of the safest places to carry valuables is in a pouch or money belt that you wear underneath your clothing.
You should always photocopy important documents such as passports,visas,airline ticket,and take ones with you. As a precaution,don't keep everything in the same place when traveling.
