5G Technology could identify civilians with gait and heartbeat analysis
Could be central goals of 5G deployment projects.
Mastercard is investing in this:

This can already be done with ordinary WiFI hardware. See multiple papers about it:

How much easier will "device free localization and identification" be with 5G's higher frequencies and beamforming antenna arrays?
Why else would people be writing papers like these?
