Banks can track each banknotes serial number when you receive them from the ATM and when they are returned from the store you spent them at. This data could then be used to create a complete profile of your spending habits.
Doesn’t work very well if you buy something directly from someone. Or if your cash is given out as change. Seems like it would make a wildly inaccurate profile.
Lots of stores also gives bills back out, the system makes zero sense, it can’t track anything at all. Like maybe 5% of bills are used once and then returned to the bank.
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.
ATMs give out $20 bills. In order to get one back as change you’d have to pay with a bill larger than $20. I don’t remember the last time I carried something larger than a 20.
Given a large enough time frame this can be treated as random noise which is easily filtered out, and this data isn’t necessarily meant to track your supermarket shopping. For example, you can use it to figure out where somebody went who has gone into hiding. They might have cleared out their bank accounts before leaving and with that data you can see where these banknotes are now showing up. Just wait at the store they apparently visit every Tuesday.
I’m a tradesman and get paid in $100 all the time. A guy from the city gave me $100 for a job. My wife, who is a treasurer for Girl Guides, traded her cookie money of $10’s and $20"s for my $100 and deposited it in the bank. Now the FBI can prove that my customer has an unhealthy cookie addiction.

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.

They give out $100’s if you aren’t a poor people.
But seriously though. A lot of ATM’s will do 100’s, anymore.
Bank ATMs can give out any denomination.
Not in Canada. It sucks.
Well I’ve never seen those. Must be new or Desjardins doesn’t have them.
That’s a credit union, not a bank. Just like 7-11 atms won’t have them either, it’s only bank atms at the branch’s.

It’s like a machine that behaves as a bank teller, kind of automatically.
