The first encounter with US border technology is usually near the Darien Gap. The Darien Gap is a mountainous, jungle covered region between Panama and Colombia. It serves as a common yet treacherous pathway for those hoping to make their way north since the relative ease of obtaining South American visas gives migrants an entry point to the hemisphere. Aware of such journeys, the US has supplied the Panamanian border security force, SENAFRONT and Costa Rica with equipment to collect biometric data from everyone that crosses their borders.
