Wallet: Include in your wallet only what you must and leave the rest at home For travel, an outdoor, waterproof, wallet with Velcro closures is a good investment. Consider a shocking-orange or lime-green colors, so bright that it shouts at you if you leave it carelessly. Keep a photo-copy of all your cards somewhere safe in a separate location. In addition, carry a recent photograph of all people travelling in your party, just in case you lose sight of someone. Save a copy on a cloud drive facility.
