The Gang of Eight scheme provides for all sorts of high-tech measures to be put in place along the southern border. It spells out in excruciating detail the number of motion sensors, drones, cameras and other devices to be employed.

Probably more significant, from a technology perspective, is immigration reform’s reliance on a massive new information program based on the E-Verify system. The project would connect every employer in the country with a central database to check whether prospective employees are in the country legally.

The Gang of Eight proposal also requires background checks, relying on other centralized databases, for the estimated 12 million people now in the United States illegally. And then there is what is known as “entry-exit.” That is a nationwide high-tech system to track every person who enters the United States on a temporary visa, recording when that person arrives and leaves.
