I do IT support for onboarding remote hires for a call center we catch about 1-2 hires a day who are fraudulent. Most we catch by comparing the photos on their DL to the person who shows up on webcam for training. It’s unclear the motivation for the fraud. I don’t think they really have dug into that yet.
Should be possible to store digital music on cassettes as well just like you would with a tape backup. Would probably increase both the quality and storage capacity of cassettes.
I always thought this would be a good use for inexpensive flow meters with network/wireless connections. They would make it possible to find the points between which water is lost. Even in a home or large building have network capable meters should allow you to track the points in the plumbing where the leak is or at least the run of pipe containing it.
