Companies across the globe are grappling with reopening their physical places of business in the coronavirus era. Businesses and governments have taken to location tracking, thermal recognition, and temperature checks to identify individuals potentially sickened with the coronavirus.

These surveillance methods have implications for individuals' privacy and may be regulated by privacy laws such as the California Consumer Privacy Act (CCPA), which counts thermal information as protected private information.

Big technology companies such as Google and Facebook and various governments have also launched coronavirus tracking apps. These apps use Bluetooth technology in mobile devices to conduct contact tracing with the goal to identify the source of coronavirus infection spread. But these are generally optional, require users to own mobile devices, have end-user privacy implications, and can be riddled with false positive and negative errors.

Is there a more accurate, consent-given way for companies to grant access to physical spaces in the era of coronavirus?
