A Home Office spokeswoman said: "The data encoded to the chip in the biometric passport is securely stored and contains no more personal data than the information printed on the data page of a passport.
"There is no evidence to suggest anyone's personal data has been stolen from a passport's RFID chip. The passport chip does not have the same communication protocol and therefore it is not physically possible for the chip to be read from the distance suggested."
I've made no secret of my curiosity about the RFID-blocking passport holder.
The Home Office seems to be responding to the article that inspired this post (and probably many others).
