It's probably for "Security" reasons, as if they were before Customs,
any member of staff going to maintain or 'top up' the machines would
have to have an airside security pass, if memory serves.

And it's highly unlikely that anyone carrying a million quid in cash is
likely to pass the background tests and qualify for a security pass.

Meanwhile every spotty kid serving in the Dixons in the [airside,
obviously] departures lounge has a security pass he found on the back of
his box of breakfast cereal.
