I always thought it was silly to have separate toilets for staff / workers / managerial persons in organisations. My rationale was that we all have the same biological systems for excretion and physiological relief. It is not that different levels of the organisational hierarchy are Physiologically different.
The installation of smart cards is interesting.
During the early days of the debate on UID, a justification was that it has "millions of uses".
Application builders should note that the UIDAI application portal would soon be updated to include smart toilets to enable application development in the area.
Well, here is another use of UID, perhaps the best way it could be used.
After all, if the government is feeding the poor by uniquely identifying them, the government must uniquely identify those who excrete, as an audit to know how much of the intake is coming out!
The input / output ration would indicate whether the welfare benefits are actually reaching the beneficiaries!
