These days most people don't use travelers cheques, plus once you get to some places such as India, it is a massive mission to get them changed and some banks will not even consider changing them.
I take a little cash in a wallet, then two debit cards, one hidden as a spare. If I am further a field, for emergencies I hide some money sealed and water proofed on the bike. I've also laminated dollars in what looks like a membership card before which is in my panniers and avoids the eyes of officials going through my stuff at border crossings.
The other thing people sometime use in far off places with a bit of a reputation for crime, is a muggers wallet. This consists of a cancelled credit card or two, some cash & other wallet like things, pictures of loved ones, just be creative. If you are held up, just hand it over and the robber should be happy.
The other thing I do if I am on the road for a while, is gradually transfer money over the internet into my debit account, from safe internet hook ups. That way it I lose the card, there is not too much money to lose.
I also email myself and take a copy of the numbers to call to cancel my cards.
I always use cash and never pay for meals of rooms with credit or debit card, to avoid cloning and so on.
Hope this helps.
