Part 4/7:
This system allowed hospital employees—around 25,000 in total—to assess their symptoms, exposure history, and travel risk via a simple app each morning. Based on their responses, employees received either clearance to work with a digital badge or instructions to stay home and follow up with occupational health services. Those cleared to work showed this badge at the entrance, effectively functioning like a digital TSA PreCheck—minimizing wait times from around 25 minutes to just a couple of minutes during peak hours.
