RE:RE:RE:RE:TSA Approved Vendor ListI suspect that there may be different TSA approved 'technology lists'. Likely in the following categories:
-Passenger Screening - walk through metal detectors, wands, X-Ray, CT, trace explosive swabs (XTRA might fit in this category?)
-Credential Authentication Technology - pastport / ticket / ID scanners)
-Checked baggage - X-rays, swabs, etc
-Air Cargo Screening
