Smart card / auditable access for rack KVM tray

Is there such a thing as a KVM Tray for a standard 19" rack whose use can be validated by a smartcard (or some other auditable authentication method)?

It looks like we have a security requirement where just because users have a key to the rack doesn't mean they will be allowed to use the console inside the rack, and rather than just lock the console (and keep track of who has keys), we would prefer to be able to audit the actual user that was attached at the KVM.

(It's worth mentioning that I'm aware of the Raritan devices, but they surely can't be the only ones)

_{(If these things existed, I don't think half of the tratoirs that somehow manage to infiltrate CTU on the TV show 24 would ever get away with anything)}
