You know those boarding passes you would just toss after you got off a flight? Well, don't. Wait till you get home or at least tear it into little pieces.
Take a look at what one reporter from the Guardian was able to find out from one boarding pass. Q. What could this boarding pass tell an identity fraudster about you. A. Way too much.
The traveller's name was Mark Broer. I know this because the paper - actually a flimsy piece of card - was a discarded British Airways boarding-pass stub, the small section of the pass displaying your name and seat number.

We logged on to the BA website, bought a ticket in Broer's name and then, using the frequent flyer number on his boarding pass stub, without typing in a password, were given full access to all his personal details - including his passport number, the date it expired, his nationality (he is Dutch, living in the UK) and his date of birth. The system even allowed us to change the information.
Using this information and surfing publicly available databases, we were able - within 15 minutes - to find out where Broer lived, who lived there with him, where he worked, which universities he had attended and even how much his house was worth when he bought it two years ago.
