Last night, I wrote a posting about a Newsnight feature on the unreliable nature of chip and pin technology; about how Stephen Murdoch and Saar Drimer from the University of Cambridge had exposed the flaws in the system; about how high streets stores and banks had denied such weaknesses existed.
This morning, I found a response posted from Saar Drimer himself, thanking me for commenting on the article and attaching links to further information. Now isn't that how the Web should work?
This issue is critical to all of us - chip and pin is fast becoming the "only game in town" for banks and high street retailers. So we should expect those same banks and retailers to invest in plugging every known gap, every flaw, every shortcoming in their system.
A few minutes on BBC television can only scratch the surface. Saar and his Cambridge Computer Science colleagues have set up an excellent blogsite - "Light Blue Touchpaper" on their work, and the least I can do to thank Saar for his contact is to add the link to this to my Blog Roll on the right hand side of this screen.
Take a look - make yourself aware. It could be your card that's being cloned.
