RE:RE:Liberty’s Shoe Scanner gets Jimmy Fallon mention I think you've got some outdated information.
Re Plymouth's shoe scanner, I'm curious who they are currently beta testing with? Appreciate you talking up your own book but why does Plymouth only talk about their Wi-Fi drones now? Also, how could they advance without any treasury, they are always on the brink of running out of money.
Unlike Plymouth's tech Liberty's newly licensed shoe scanner was funded by the U.S. Department of Homeland Security (DHS) and developed at the Department of Energy (DOE) Pacific Northwest National Laboratory (PNNL). Liberty was granted a license to commercialize this tech. The TSA is currently testing Liberty's shoe scanner.
The DHS Apex at Speed Program you have included is referring to Liberty's shoe scanner.
