Registration, queue and the waiting room screen

Registration that asks the right things once

Identity, citizenship, panel membership and allergies are captured at the counter, because each of them changes something downstream: citizenship decides the tax treatment, panel membership decides who pays, and an allergy decides what the doctor is warned about an hour later.

The queue everyone can see

One live queue, shared across every workstation: who is waiting, for whom, how long, and what state they are in. The doctor's room and the counter are looking at the same thing, which removes most of the shouting across a clinic.

The waiting room display

Any Windows PC with an HDMI cable to a television. It shows the numbers being called and nothing else — no patient names, because a waiting room screen is a public place.
