People who want airgap security are very cautious about USB > keys these days. I agree, it's a bit similar. Except that the voucher is a signed entity, and disclosing it causes privacy issues (people know what you have), rather than being p0wned. It can easily go on a CDROM or something else you do trust. A QR code is also possible, assuming your personnel-safety-critical device has a camera. [oh. Now I'm thinking about 2001, Space Odyssey. I'm seeing Dave Borman with a giant QR code tattoed on him, much like we proposed doing with the RSA algorithm back during the cryptowars of the 1990s ] {and the issues with USB devices are squarely a problem of GUIs accepting input devices without validation.
