Nonresident Travel Money (Card or Bank Account) Solution with Emergency Cash Feature in Euros?

We haven't received a response on what country this is relevant to. In such a situation, I can't give a country-specific answer.

Both Visa as well as MasterCard maintain a database of prepaid / travel card providers. Most prepaid cards are explicitly targetted for people who may not be eligible for normal banking services. Try to choose a credit card from a multinational travel agency, rather than from a country-specific bank, and you'll have a greater chance of getting some form of financial assistance when travelling abroad.

For a true emergency, carrying cash, hidden somewhere on your body/inside your clothes is still the best option. If it is hidden well enough, nobody will likely ever find it. The problem with any bank card / bank account option is that you will need the card or some form of ID to access your money. If you can hang on to those, you could as well (even easier) have some cash instead.

When I travel, I carry around cash. Hidden at two or so 3 places. I've met quite some travelers who do the same. You only need enough cash to last you long enough for renewed access to your bank account; so 2 or 3 days worth of emergency money should be plenty.
Common locations seem to be inside your shoes, inside belts, inside bras and in special pockets on the inside the leg of your trousers.

I've talked to people who have been drugged and robbed in South America, everything was stolen, except for their trousers and her bra (yes, shirts, shoes, passports, etc. were all gone). Yet, they had enough money to get to a hostel and wait for their emergency passports be made and money to arrive by bank.

At your local bank is it possible to send money to other (International) bank accounts (using an IBAN, for example) completely online, without needing to go into the office and sign papers? This is a common feature in most European banks and I use it often.

If so, then in the worst case scenario you can login to your bank from abroad and transfer money to a close friend or relative's account and have it in your pocket within 1-2 days. You could also open a new account in the new country you are in, but sometimes this is a bit difficult with paperwork.
