That's already the original use case. Cardiac signature biometrics, can install in a doorway and do identity verification and track/monitor every individual that passes through the threshold
People do not have that distinct cardiac ECG profiles, and it would be wrong after one coffee.

The article you cite states that accuracy drops to 60% if the enrollment and testing data were collected at different sessions. I imagine the effects of coffee or walking on heart rate would make that even worse.
