Yet somehow there are twice as many Amazon Go stores in Illinois than in California [1]. And biometric-based time-tracking for hourly employees is extremely common. It's because the Illinois law doesn't prohibit biometric collection and use, it prohibits collection and use without explicit permission of each individual person involved. [1] https://en.wikipedia.org/wiki/Amazon_Go https://en.wikipedia.org/wiki/Amazon_Go PS - Illinois also prohibits discrimination against employees that do not consent to biometric-based tracking and thus all of the systems for sale in Illinois have traditional methods that can be used at all times.
