Since the Taliban has the full biometric database along with the scanners and other equipment, that necessarily means that Russia, Iran, and China have this equipment and information as well.
That means that every service member, government worker, embassy staff, or spy has had all of their biometric data compromised. It means that Russia, Iran, and China know exactly who and where they are. Also, there is no guarantee that the database does not include biometric information on spies and collaborators all over the world, not just in Afghanistan.
With the equipment and information in their hands, advanced foreign powers like China and Russia will be able to reverse engineer the technology which gives access to restricted information and restricted areas. No doubt, within a few months they will be able to spoof this equipment and get their spies through any screening or checkpoint anywhere in the world.
Since this information and equipment has been utterly compromised it is now defunct, and has been rendered useless as any kind of a security procedure.
