The interface is very friendly -- it's so simple that I find it compelling to use. A button press doesn't take any time out of my day or any data I wouldn't want to share. (Hopefully there are no strings attached e.g. video monitoring.)

When they started appearing near my local pharmacy, it was placed next to a stand of toys with giant cute eyes, which drew my attention to the "matching" happy face. Nice job on strategic placement, I thought.

Reading the article, yes, you're leaving more information than you think (but maybe not more than you're willing to share).

Video monitoring is mentioned in the article together with timestamping. A store had a "customer satisfaction" problem in the morning, so together with video footage, they could determine there was slow-starting employee who was at fault.
