A major problem with that technology is it simply is “racist” by design. Now, let me give context to that.
The vast majority of research into facial recognition technology was done with white subjects. Therefore, the technology tends to work better with lighter skinned people. The darker your skin the more biased the technology is against you and the more likely you get pulled aside because it doesn’t recognize you. This was a part of the case the ACLU was making, and it still applies to its usage in a theme park.
I personally feel that a technology that singles out darker skinned people should not be used anywhere until the proper due diligence has been done to change the current statistics. We sadly are not there yet.
Also, I don’t remember where I read this, but I believe it has more trouble with women as well as it was also mostly tested with males. I can’t verify this though bc I haven’t looked into it enough. This is actually an interesting phenomenon in medicine that in the past decade has started to be corrected. The “average person” used with FDA approval of drugs was a white middle aged male. John Oliver did an episode on this last point on Last Week Tonight a bit ago. I recommend watching it.
