Australian pubs are starting to use facial recognition in areas with gambling machines, to keep people out who have requested not to be allowed to gamble.

The basic idea sounds harmless in principle. It would seem that if you have not added yourself to the list of people to exclude, this system won't affect you. But is that really true?

I wonder who else will have access to the face scans of people who visit the club? Will those scans go into a system connected to the internet?

Will state agencies be able to add faces to the list of people to exclude? Will state agencies be able to collect the face scans of everyone that enters?
