Sam Fisher- OPSAT Fingerprint

  Fisher pulled back the cuff of his jumpsuit and pressed his thumb to the OPSAT, or Operational Satellite Uplink, screen, which glowed to life:

  // . . . BIOMETRIC SCAN ENGAGED . . .

  . . . SCANNING FINGERPRINT . . .

  . . . IDENTITY CONFIRMED . . . //

  There was a flash of static, and then the screen resolved into a gray-green satellite image. The biometric scan feature was an upgrade to the OPSAT, designed not only to prevent prying eyes from using it, but to keep an inadvertent bump of the touch screen from changing modes. During his last mission, Fisher, on the run, had found himself suddenly staring at a map of downtown Kyoto, rather than the schematic of the Nampo shipyard he was trying to escape.
