Each person must present their completed health survey certificate at a check-in desk and they then receive a color-coded wristband that allows them to be on campus for that day only. Between 8AM and 10AM, the average arrival rate to the check-in desk at the business school building is 30 people/hour. It takes 90 seconds, on average, to complete the check in process.
