Casinos have been tracking you for a while now. Think of how many cameras are around you at any given moment.

This has been the case for a long time. This is one my my favorite movie scenes about it: https://www.youtube.com/watch?v=RH0VGDi_oIY

edit: I had too many this's

When the first casino in Atlantic City was built it came with the cameras shown in that video, in 1977-78 when it opened. I worked in that casino at that time and the cameras were common knowledge.

I believe they were already standard retrofit in Las Vegas years before that.

I think the movie is a great movie, and accurate in a certain way, but if you tried to timeline anything using that movie, it could get confusing.

Why would the ACLU care? It's a private entity doing a private thing. It's not like it's the TSA, a government agency, gate keeping a public form of travel.

The line isn't as sharp as you might think.

Certain private spaces are considered "public" in some regards, such as right of access and some free speech rights (e.g. handing out pamphlets in malls).

Also some "public" spaces are privately owned (e.g. the park where Occupy Wall Street got its start was supposedly open to the public as a condition of getting some building permits, yet the landowner spent money evicting the occupiers).

The casino isn't free to bar people of certain races, and it may have other restrictions as well. Though spying is presumably unrestricted :-(.

The line is extremely sharp in this case.

None of the things you refer to has any meaning as it pertains to the private spaces within privately owned casinos. A casino lobby in Las Vegas is not considered a semi-public space like a mall. That was settled a long time ago (it's why the porn pamphlet people can't go inside the MGM and pass those pamphlets out in the lobby).

All the privately owned casinos in Las Vegas can legally do this. A challenge to it in court wouldn't get anywhere.

They can't legally put hidden cameras in their toilet stalls or hotel rooms, why would they be able to legally put systems that can obtain a nude image of someone without their consent on the casino floor?

If the casino owner were going around the taking furtive pictures up girls' skirts, would you still think it was clearly on the up-and-up? The fact that it is private property doesn't mean you have unlimited rights to do what you will to other people there, particularly without their consent.

I'm not sure the ACLU will have a problem with it. Private entities can have conditions for you entering their land. It only becomes a problem when the government does it.

> Is this considered an invasion of privacy?

No.

> I wonder if they can track you with this tech.

About as well as anti-theft gates at Macy's track you.

>About as well as anti-theft gates at Macy's track you.

anti-theft gates don't have imaging capabilities.

Neither does the technology in the referenced article...

Yes.
