cypherpunks comments on Printers leave a watermark on each page indicating the exact printer that it came from. Are there any other examples of these privacy violations that aren't common knowledge?

I ONLY give other people cash, all my other purchases are debit/credit.

If you always use card payments whenever it's possible, it obviously isn't necessary to analyze your cash transactions to learn where you are because you are already disclosing it :)

Like MOST people and stores since Covid

There are close to 2 billion unbanked people in the world. In the US, it's less than 6% nationally, but over 10% in some states.

Many people who are not unbanked also often avoid electronic payments for privacy/security and other reasons.

The cash serial number tracking being described in this thread is useful for locating the neighborhoods frequented by someone who (a) avoids using electronic payments, and (b) maybe obtains cash from an ATM (or perhaps check-cashing service, in the case of an unbanked person) in places other than the neighborhoods they live in or frequent.

……

If they don’t use a bank, how are they pulling money out for it to be tracked?

See, none of it makes any sense lmfao.

Which is useful to who…? The only time that information is useful, would be for an investigator, so… again… someone, boots on the ground, and doing visual verification. And an investigator and plenty of other useful metrics with less noise.

Reality!

The person originally started talking about spending habits, and shifted to finding criminals. Those are two whole-fully different situations that need different information points, and are also gathered in significantly different methods.

One example I mentioned in my comment you're replying to is check cashing services. Millions of people in the US receive money via things like check or money order and need to change it to cash despite not having a bank account to deposit it in; this usually involves identifying themselves.
