Documents details a tool named ExpressLane that the CIA uses to ensure that fellow liaison agencies share the collected biometrics with the CIA.

According to the files, the CIA designed its biometrics database in such a way that the entire system ceases to work after six months if a CIA operative doesn’t visit the liaison agency to install an update.
