Our government and other big companies have been funding digital/biomedical/wearable vaccine passport research for a long time.

The CDC already has procedures in place for monitoring people they believe may carry disease, via electronics and wearables:

“HHS/CDC has proposed a definition for “electronic or internet-based monitoring” that defines this term as referring to mechanisms or technologies allowing for the temporary public health supervision of an individual under conditional release, including electronic mail, SMS texts, video conference or webcam technologies, integrated voice-response systems, entry of information into a web-based forum, wearable tracking technologies, and other mechanisms or technologies as determined by the Director or supervising health authority.”

For global travel and trade to return to pre-pandemic levels, travelers need a secure and verifiable way to document their health status as they cross borders.  Countries will need to be able to validate a traveler’s record of a COVID PCR test or vaccination administered in another country. Countries will also need the flexibility to update their health screening entry requirements as the pandemic evolves and science progresses.  Airlines, airports and other travel industry stakeholders will need the same.

The Commons Project has developed CommonPass to address those challenges.
