False Positives
And how many people were denied passports or had considerable trouble getting one because of the system.
Does the system discriminate on facial colour?
The Passport Office has stopped 600 fraudulent passport applications using a facial recognition system it rolled out as a pilot across its fraud units last year.

From what I've seen of such software in documentaries, it relies on absolutes such as the distance between the eyes, length of nose, width of mouth etc or some combination thereof.
If the eyes are a bit closer together or the nose a bit longer in the photo, that could be enough to fool the machine whilst the human eye (especially backed up with a bored brain!) is quite capable of ignoring or missing such changes.
