A little old, but interesting. I stumbled across this on Flickr:

ATM fraud in action at Tesco
Created by bowbrick.

I helped to pull this entirely convincing card skimming false front from an ATM at Tesco in Radlett. Its appearance was perfect in every way – we sussed it out purely because it looked different. Anyone who hadn’t used the machine before would, presumably, have happily inserted their card. The thing was stuck to the ATM with a few strips of double-sided tape and had obviously been applied hastily. It was logical to assume that the perps (as we call them here at CSI:Radlett) were still present and close enough to read PINs.
