It has been several weeks now since I read the article that I had in mind, but I have found this other article[0] on the use of wristbands to enforce quarantines, and towards the end it mentions the possibility of wristbands for contact tracing that I posted about above. It is easy to assume that if such tech exists, then governments will expect you to use it if you are one of those weirdos like us (or very elderly) who don't have an Apple or Android smartphone.
