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? (ttrpg.network)

One thing I'm concerned about is recording equipment leaving identifiable information without us knowing about it.

They don't give $100 bills back out.

    For cashback? Why wouldn’t they. That’s also why this system makes no sense, avoid the atm, use cashback. Fuck everyone’s metrics up.

    Most places don't do cash back, and the ones that do tend to have a limit of like $40. Wal Mart is a bit of an exception, as they'll do $100, but you aren't getting a $100 bill from them through their self checkout. You'll only get 20's.

    So if you go to Wal Mart, and you go to one of the few real people to check you out, and you ask for it back in a $100 bill, and the teller happens to have gotten a $100 in since they had started that day, and the front lead hadn't already cashed out the register since they received that $100 bill, then yes. In that case you'll get a $100 bill and will slightly fuzz up the tracking metrics they could theoretically do.

    I would expect a couple hundreds back if I use a thousand dollar bill.

    Still legal tender, still required to be accepted.

    There’s Noise everywhere, it’s a neat proof of concept, but it’s not gonna be used for what the user claimed.
