I'll be honestly surprised if this is stopped instead of just being quietly picked up by governments now they can see the potency of such a tool combined with a national database. Combining something like this with proper security controls/automated kiosk things, you can literally tell people to leave things like secure locations without them even seeing a person.

If a company can sell this to a government and get leniency/immunity from lawsuits like this, they'll become pretty much essential to national security, a strong position to be in.
