Protect your credit cards and account numbers
Everyone knows about credit card theft, but even if your actual, physical card isn’t stolen, your account number can still be copied and used fraudulently. This type of identity theft can be disastrous because your credit reserve can suddenly disappear in the middle of a trip.

Don’t advertise the fact that you’re an American
It’s great to be a proud American, but don’t broadcast the fact while traveling in foreign countries. Americans are popular targets for casual theft, robbery, and worse. Consider getting a generic cover for your Passport. Avoid flashy and expensive jewelry and watches. Leave the good watch at home and wear an inexpensive one for the trip. Or just wear the better jewelry to special events.

Protect your property and identity
Protect your luggage, electronic gear, and other valuables at all times in public and private places, including airports, hotels, and restaurants. Don’t assume that your property is safe in your hotel room. If you must travel with valuable personal items or documents, ask the hotel manager to keep them in the hotel safe when you’re not using them.

Protect your credit cards and bank card account numbers and PINs.
Check with your bank to make sure your ATM cards are compatible with enough bank locations in countries where you’re traveling.

Be aware of local laws and health considerations
Laws vary among countries, as do health issues and availability of medications.
