Further to recent conversation about RFID, we don’t like to quote the Daily Mail as a source but its 5 March story on passport cracking is worth bearing in mind:

‘Safest ever’ passport is not fit for purpose In just four hours, the Mail hacked into a new biometric passport and stole the details a people trafficker or illegal migrant would need to set up a life in Britain. With out even opening the envelope containing the passport.

There are less fishy uses to which put RFID chips can be put, like library books - even the Vatican uses them.
