Also, if you have business cards showing who you are or where you work like ( software development engineer , IBM ) , it is a good idea to distribute a few in your wallet, purse, backpack , and a couple in your car's glove compartment.

Such cards are good to be on you , and not too bad if lost or stolen.

Also, double check your communication options.
For example, what if your cell phone is lost, stolen, broken ??
I do have another older cell phone that I take on critical trips.
