My local Supermarket (one of the top 3 in the UK) has modified its self-service checkout tills to include a CCTV camera about 1.5 meters vertically above the credit card reader pointing straight downwards at the keypad. I'm sure there are legitimate reasons for doing this, and the camera can record any potential theft, but at the same time I really can't believe this can be legal? The camera is fixed, the credit card reader is also fixed (it can be angled downwards a bit, but not removed from camera sight). This has got to be a major security breach, I'm sure the images aren't publicly published online, but I'm also pretty sure that the security personal that can view it are underpaid and subjected to only basic background checks.
I know that fixing a camera to record pin-numbers at a bank ATM machine is illegal - this features in occasional news stories, so how can it be legal for a supermarket to do the same thing?
