  • With the newly developed shoe scanning technology – plus improvements to existing body scanners – passengers can get to their gates faster.

The improved screening technology was developed at the Department of Energy’s Pacific Northwest National Laboratory and funded by the Department of Homeland Security.

  • PNNL developed the body scanning cabins that have been in use at airports around the world for around 15 years.
  • They came across the shoe scanner while working on a high-resolution body scanner that could better detect threats while reducing false positives that require secondary screening.
  • PNNL recently licensed both technologies to a security company called Liberty Defense Holdings. Liberty plans to install them in airports in about 18 months.
