COVID PreCheck is a screening app that's launching later this month to offer "TSA PreCheck style clearance" so that people can safely return to work. Participants are directed to their local blood test collection center so that they can take an antibody test. The lab results are shared straight to the app, as "the level of antibodies in a person's system will determine their 'pre-clearance' status." COVID PreCheck app users can then present a QR code to their employer to verify that they're at a lower risk for COVID-19 and therefore safer to interact with staff and the general public.
The app relies on secure blockchain technology to protect user data and privacy, and the app has the potential to offer a sense of security in cases where there's public concern.
