Your life in your pocket
It's frightening how much sensitive data that people walk around with on devices that are easily stolen, lost or confiscated. In decades past, if somebody picked your pocket or demanded you forked over a wallet or purse, they could get away with whatever amount of cash you had and that was pretty much it except for the hassle of having to get replacement ID, etc. These days people walk around with all of their banking information for not only their checking and savings accounts, but brokerage accounts and retirement funds along side of all the information somebody would need to create access to those accounts. Think about how hard it would be to figure out how to put stops on accounts if your phone/laptop/tablet were stolen while on vacation/business in a foreign country. Hopefully, you have your credit card information written down in a separate location along with direct phone numbers (toll-free numbers aren't universal) so you have the possibility of canceling them and getting a replacement while abroad.
Just like iTunes lets you make different playlists that you can sync to your iDevice, the same thing can be done with other mobile devices. Create different phone number lists for everyday and travel. Put your sensitive data on an external drive that you keep at home. Be aware of what might be considered pornography in different parts of the world if you travel. The cover of the Sports Illustrated swimsuit edition is pornography in certain countries (it's not hard to make a list). Certain "R" rated movies will be classified in the same way. Articles or writings about politics and religion are often banned by the more extreme forms of "government".
If you travel a lot, get a separate laptop/tablet that is stripped down to the essentials. Access to your retirement accounts is not essential. Pictures of your young children frolicking in the lake last summer holiday with no swimsuits on may get you the death penalty in some quarters. Ask yourself if you really need a file or application when you load up the drive/storage. Do the same thing for any device that you tote around when in your own country too. There is no law in the US that prevents an officer from asking to look at your electronic device. If you agree and hand it over, that's a voluntary act when they may have to get a warrant to make it a demand.
If you have to travel with sensitive company information, put it on SIM card or other easy to conceal device and stick it to your shin under a bandage. For an extra bit of camouflage, put a drop of iodine on the bandage so it really looks the part. Mix applications and devices so one has to be plugged into the other to do any good.
Convenience and security have a tendency to be the inverse of each other. An app that makes it more convenient to access money probably means those funds are less secure. When I travel by car, I always have cash to pay for fuel to get me home or at least a full tank or two just in case. I've pulled into several stations in the last six months to find that their credit/debit system is not working. This will be almost guaranteed in the case of a hurricane, earthquake or other natural calamity. Sticking with cash for many purchases also puts a limit on impulse buying.
Singling out the US is counterproductive. The travel ban (if you take the time to read it) is not about religion, but about restricting travel by people from countries where most of the citizens love to take to the streets and shout "Death to the Americans". Not exactly the sort you want to invite over with a guilt edged invitation. Many countries are trying to look like they are doing something to prevent terrorism and the efforts so far have been right on the mark… They are doing things that LOOK like they are preventing terrorism. The game is afoot. Understand the rules and develop tactics to stay one (or several) steps ahead and there won't be bars on your windows and doors that lock from the outside only in your future. Even if you don't think you have any secrets (lucky you) there are lots of things you should keep private.
