If, like me, you're taller than average, checking an ATM for unauthorised after-market enhancements before use can, in itself, look suspicious.
You have to stoop to the level of the screen and look upwards, checking for anything out-of-the-ordinary.
Alternatively, you have to run your hand over the invisible upper part of the machine, and thereby exposing yourself to the risk of running your fingers through last night's semi-digested chicken korma.
This simple mirror-backed wallet held over the data-entering hand combines the function of shielding prying eyes from ascertaining your PIN, whilst allowing a thorough yet discreet inspection of the machine.
