In late 2020, a large box arrived at Juan Gilbert’s office at the University of Florida. The computer science professor had been looking for this kind of product for months. Previous orders had yielded poor results. This time, though, he was optimistic.

Gilbert drove the package home. Inside was a transparent box, built by a French company and equipped with a 27-inch touchscreen. Almost immediately, Gilbert began modifying it. He put a printer inside and connected the device to Prime III, the voting system he has been building since the first term of the George W. Bush administration.

After 19 years of building, tinkering, and testing, he told Undark this spring, he had finally invented “the most secure voting technology ever created.”
