Except most people use multiple cards, multiple banks etc. there will absolutely need to some visual verification to be able to ever establish a starting point. It just doesn’t work.

It’s a neat proof of concept, but in reality, that would never hold up in court.

Give your head a shake, I’ve got a bridge to sell you if you actually believe this is being used or can be used for what you claim.

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.

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.

…

Those are done at a teller, not an ATM. An ATM requires a bank card, cashing a cheque at a teller does not. The post and everything that’s being discussed is about ATM tracking…

It doesn’t make sense when you actually understand how the system works…

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.

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.

……

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.

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.

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.

Bank ATMs can give out any denomination.

I ONLY give other people cash, all my other purchases are debit/credit. Like MOST people and stores since Covid

The only time this works, is if it’s targeted, and that means an investigator is doing it. An automated system wouldn’t know what to do with any of the data. You’re severely overestimating how much people spend cash around them, that’s usually when it’s plastic. People use cash in “sketchier” places.

Again, zero basis on reality, it gets “destroyed” at every step without some manual intervention.

Without some type of visual confirmation, it’s all noise.

On my way home from work, I grab $600 from the atm, $300 for my wife’s tattoo, $200 for me, and $100 for wife spending money.

After the appt the tattoos artists wife takes $200 and flys across country that night. I spend my $200 at the peelers, all those go to a dozen different girls and servers. My wife the next day goes shopping at an outlet mall and spends her $100 at 4 stores. The tattoo artist spends his $100 on beer.

We live on the same block and I pulled the money out across town. Who’s is the original takers purchases….?

It’s 95% noise, it’s useless unless you’re an investigator and have boots on the ground.

Again, it’s a fun story to share around the campfire though. Is it possible, yes, can it be done in actual practice, absolutely not. Not without some other information.

That’s completely made up. Most bills are given out to other customers once used in a store, the amount of bills that are used once and returned to the bank would be well under 5%.

Fantastic fabricated story though.

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.

Gunpowder…?
