How many of us ever put a camera down on a table on holiday and forget it?
Try this:
Write your name and address and phone number on a piece of paper.
You can also add your passport numbers if you like.
The next bit is simple... take a photo of it!
If someone *honest* finds your camera, they then have a way of returning it to you.
Likewise if you lose your passport you'll have a record of the issue number.
The dishonest ones won't take a blind bit of notice... the camera was lost anyway so nothing more is lost.
I was also asked, "what about identity theft?"... Well, it's an issue I suppose, but I don't see any more info here than what's pretty much available in a phone book.
Like any tips or tricks, use the info if you like, discard it if you don't like
