TSA is redirecting their attention back to shoes. According to the Office of Federal Business Opportunities, TSA wants a shoe-scanning device that can detect threat objects concealed in footwear without requiring passengers to remove their footwear as they pass through a security checkpoint. These threat objects include a wide variety of military, commercial and homemade explosives or explosives devices.
According to TSA, the removal of footwear takes time, reduces the efficiency of the checkpoint, creates safety concerns with footwear removal and contributes to passenger dissatisfaction. In addition, scanning footwear through the X-ray machine increases the volume of items that the TSA agents at the X-ray machine must visually screen.
With new SSD technology, TSA hopes to reduce the number of passengers required to remove their footwear, perform screening without increasing TSA agent staffing levels and increase overall operational throughput.
