If I had a 3D model of my body and measurements, I could send that to a designer for custom tailored clothing, which could then be cut and stitched by a 3rd party. Does a service like this already exist? Maybe an IPad is sufficient precision for the 3D model.
With the rise in scraping, impersonation, identity falsification? Not even slightly interested in full body scan tech.
Driver's License? The crooks will probably have a much easier time than me going to the DMV.
Put you somewhere you weren't with video generators? Hey, they've got a hi-res, full-body naked file of you for reference on video addition and substitution.
Why does the IRS' think this account's more me than me? Much better at video substituting your fake face for ID.me than the nonsense of you trying to use the ID.me cell phone app.
Print your face out as a mask Mission Impossible style and use your identity during robberies. The list goes on and on.
And these people never seem to delete anything properly, no matter how much you check. Ex: See food kiosks that photograph every customer, for some reason, with no deletion. (was in a college or factory somewhere earlier)
