Officers were verifying travellers from paper logs and unconnected workstations, with no biometric check on the holder and no perimeter on where staff could operate. Manual MRZ entry: Passport numbers were keyed by hand, with no checksum to catch transposed digits before the wrong record was opened. No holder verification: Nothing tied the person standing at the desk to the photo on file — impostor cases relied entirely on the officer's eye. No offline operation: A dropped link at a remote post meant traveller histories could not be pulled, halting the queue. No perimeter control: Officer credentials worked anywhere — there was no enforcement that an officer was physically inside the assigned border post.
