The scam you are talking about with the tape is called a "lebanese loop " , not too common in the Uk as the favourite one seems to be an entire false front to the Atm itself . To discover this you would have to grab the machine and try and move it about . Other scams are a pin hole camera above the card slot and then a further one in a "leaflet" box attached to the machine - both then record what you are up to .
Finally the biggest one to hit the area i work in is with Shell fuels - pin hole camera in ceiling , next thing you know is a withdrawal at the Bank of Barunde(?) .
If you have any specific queries please feel free to PM me and i will see what i can find out for you - obviously alot of the above is subject to change , we only find out when we catch someone
