Scan all important documents

Scan or take pictures with your smartphone of your passport and email to yourself. While you are at it, email all confirmation numbers, itineraries and international telephone numbers for any credit cards to yourself as well or organize them in a folder in an internet app such as Gmail. As long as you have that smartphone in your hand, take a picture of your purse and your suitcase. You will probably never need them, but they could come in handy if either were ever to get stolen.
