Re Lift 'Buttons'
Sounds like the job for a proximity sensing access device - a simple panel
that the student shows a 'key tag' to. No contact is needed and the relative
proximity can be set on some of the systems.
I think that this would be suitable for most security functions where one is
concerned about limited manual dexterity, but require security systems at a
'relatively' low cost.
