Patients use a self-serve kiosk to confirm their arrival at an outpatient clinic. They then proceed to the receptionist to update any personal information. After that, a nurse will record the patient's vital signs. A physician will then consult with the patient and prescribe appropriate treatments. The patient will then visit the checkout station to settle payment and schedule the next appointment, if needed.
