Going by share of daily transactions probably isn't the best way to measure this as it's mostly going to reflect the usage decisions of the rich who spend lots of money. And there are many cash transactions that simply aren't recorded anywhere. Many, many more. If you go by number of people I think the amount of cash usage would be much higher in the USA. I don't have experience elsewhere. But 16% only? That's absurd. It does not at all reflect my lived experience. I do acknowledge that in high population density areas cash seems less prevalent. But most people I know use cash. I use cash primarily.
warkdarrior•1h ago
I'm in US. Haven't used cash in 15 years. Most people I know use credit/debit cards on their phones to make payments.
SoftTalker•1h ago
I rarely use cash day to day.

I do think it's also somewhat generational. I'm at the older end of Generation X. I grew up paying cash (or writing checks) for almost everything, didn't really use credit cards until my late 20s/early 30s. There were a lot of places that didn't accept credit cards back then, such as most fast food restaurants. But I switched to cards mostly out of convenience as soon as most places accepted them.

I notice a lot of people older than me (Baby Boomers and older) still pay cash more often.

And lower income people use cash a lot, I presume because they are unbanked or can't get a credit card.

> Many prefer to be tipped in cash.

Tipping is about the only time I need cash. Outside of restaurants, most people I need to tip do not have an easy way to receive digital payments.

AnimalMuppet•44m ago
"Prefer".

I have read that, if you tip with a card, the business gets it, and they may give it to the staff, and they may not. But if you tip by leaving cash on the table, the staff for sure gets it, and the business can't stiff them. So, yeah, the staff probably prefers it.

lawlessone•1h ago
I usually tip delivery drivers in it. Other than that i don't use it.
pcdoodle•1h ago
Cash has near zero resistance (USD at least). Good property for day to day IMO.
mikewarot•1h ago
This assumes cash transactions are actually recorded. Given the increasingly invasive surveillance of digital transactions, I expect the numbers and reality to diverge more as time progresses.

Also, to be pendantic about it, I've never actually seen someone spend hard cash, just fiat currency, which has much lower value.

I do keep a US Minted dollar handy, should the need arise for hard currency. Made in 1901 at the New Orleans mint

edit/clarify: Yes, a 1901 Morgan Silver Dollar, a coin with a current melt value of $39.64 according to coinflation

dingnuts•1h ago
the extra value in that bill comes from the collector and historical interest; I'm not sure the US government is really obligated to pay out rare metals for your bill, if that's the distinction you're making.

Anyway, I think we as a society should normalize using silver coins for personal wealth transfer, because they are a good size and weight for not too much value, and they are shiny and make a satisfying jingle sound when kept in a bag

tom_•47m ago
It'll be a dollar coin, its value being the metal it's made from.

I use cash (USD) almost exclusively for small transactions. It's still the best way to pay if you care about anonymity and privacy.

> I think you spend less if you pay cash because you see the money.

This may be true for some people. Doesn't work for me at all. I see the money equally in digital and print formats.

BobaFloutist•37m ago
Nah, once the cash has left my bank account I see it as already gone and spend it freely.
jerlam•1h ago
My credit cards, both the physical ones and the ones on my phone, work without an internet connection.

Cash "just works" until you run out, or have too large denominations that people refuse. And there are more stores now that don't take cash at all.

olyjohn•59m ago
Well turns out that even with cash, you can still carry your debit card, just in case... Good God it really isnt that big of a deal to carry cash.
paulddraper•44m ago
Really?

I’ve had multiple places not able to accept credit cards due to internet issues.

Literally had that last week. (Library, they had to call me later for payment.)

CiscoCodex•1h ago
Just today I listened to an article from NPR talking about some sort settlement involving small businesses and credit card vendors. I want to support my local business and not have them pay the credit card charges. But the convenience of carrying around just one card vs various bills and coins is hard to give up.

I’m curious, how do you personally handle change specially small currency like pennies and nickels?

olyjohn•1h ago
Keep it in my pocket until I get home. Stick it in a jar. It becomes a little fun or emergency money. I find that using cash, I tend to not buy dumb little things as I'm out and about and don't actually carry change around all that often.
cmurf•58m ago
We may need to help them by looking at the POS interface and make sure they're using/requesting debit for debit cards.

I suspect the POS defaults to credit. But I've never looked at any of the interfaces.

I know US Postal Service somehow detects my card is debit and then requests a debit transaction because the credit card pad asks for a PIN not a signature. So maybe some POS have an autodetect option.

(See also my other comment)

Rediscover•49m ago
Cash-only here. I have not (generally) accepted pennies since the mid 1980's.

Many of the local places (Seattle - Belltown & the Market) are cool with rounding transactions to the nearest dollar, so that helps. It might also be part of being an active participant in the local society.

SchemaLoad•41m ago
I don't use cash anymore, but if I still was. I'd just chuck them all in a tub and every now and then dump them in the coin counting deposit machine at the bank to get notes back.

was asked for spare change and replied "i dont carry cash" then said to the person with me "would be a good idea to have square pay" to which a different person, literally from inside a dumpster, yelled "i have one!" and produced a phone with a square pay dongle. felt like i pretty much had to give them $5

The ice cream lady that rolls down our neighborhood. My 4 yo hears the music and freaks out. We have to keep cash around now.
cmurf•1h ago
From casual conversations with merchants, they are charged the same fees on debit cards as credit cards.

Apparently debit cards support either debit or credit transactions, and (some/all/most) POS systems are defaulting to credit? I notice I'm often asked to sign, rather than receiving a PIN prompt. That's how I know if the charge is going to be debit (PIN) or credit(sign).

And it is only debit that incurs the near cash equivalence due to far lower transaction fees.

What I find interesting is that most Asian countries have top spots, while Japan is still in the 60% range. Why is that?
LaGrange•56m ago
Because that’s the real top spot. It doesn’t take a lot of effort to realize there are many drawbacks to cashless.
hysan•51m ago
At least when I lived there, Japan was a heavily cash centric culture. Due in part to the difficulty of getting a credit card and how little benefit there was to having one for day to day consumer interactions (edit to mention that I’m very much simplifying here; I know it’s more nuanced than this). 60% is lower than I would have expected but it has been almost a decade since I lived there. I closed the article once they threw that huge pop up in my face, but I did see that they only mentioned that Japan was an outlier. If you knew anything about Japanese economics and culture, this wouldn’t have been surprising to see. I’m guessing the rest of the article didn’t provide any depth to their visualization.
anonymousiam•46m ago
So far I haven't seen anybody give you the right answer, which is that in most Asian countries, people actually have the money they are spending vs. buying things on credit.

I glanced at this and thought "they are going to make a generalization that excludes Italy". And sure enough they did, then listed it as one of two outliers.

I wonder if there's something else they are not understanding, and that their exceptions of Germany and Italy are demonstrating the conclusion doesn't fit.

Very smart; a family member just got "caught" for not redeeming use tax (in lieu of in-state sales tax) for expensive out-of-state equipment purchases brought into our state.

Penalty was 2x the local sales tax.

I just visited China and seeing it as 3rd lowest on the list makes sense. Everything is done by QR Code with AliPay or WeChat. Even the old man selling bamboo cane for less than a dollar takes it.

Some restaurants do not take cash, period - it adds a staff member. A few places like a massage parlour I even tried to offer cash instead, and they didn’t care which leads me to believe the fees are very low. Of course, it is China so there’s no privacy.

During Covid, my business slowed way down, and I took a part time job at a gas station convenience store (because selling cigarettes made be essential). The store was in a suburb of Portland with an average household income in the top 10 of Oregon, but there were also a lot of trade workers, undocumented immigrants, and generally a good mix of income levels.

Some relevant observations:

- Lower income customers used cash much more than higher income.

- Men used cash way more than women, with the exception of retirement-age women buying their smokes / wine / beer.

- Undocumented workers almost always used cash. Most were paid in $100 bills on Fridays, so they were probably paid under the table.

- Phone tap-to-pay was almost exclusively iPhone. In fact, I don't think I ever saw an Android user pay by phone tap.

- A surprising number of people didn't realized they could just tap to pay instead of running the chip.

- If the till ran out of pennies for change, no one gave a shit.

If you have life insurance, and you die of, say, cancer, they will go through all of your credit card transactions. You agreed to it. If you died of a car accident, maybe they go through it too, just to see if you were purchasing excessive amounts of alcohol. They won’t necessarily deny the entire claim, but they may deny as a gambit, then negotiate it down with your estate in a settlement.

At a minimum buy all vice purely in cash. Bars, alcohol, nicotine, marijuana, and anything that could hint at a certain lifestyle. Also protects you in civil lawsuit and divorce.

I play music part-time, on top of my regular day job. I still get paid in cash quite often, both by the venue and via the tip jar. I give it to the kids, if I need to send them on an errand.

I also keep some singles in my bass bag, to tip bartenders. Most venues provide free drinks to the band, but then there's no way to give a tip unless I bring some cash.

Cash payments virtually disappeared after Sarbanes-Oxley, but have come back. Also, bandleaders are mostly using Venmo or its competitors when the band isn't paid in cash.

pessimizer•26m ago
Me. I don't want every single movement I make during the day recorded in a database by people who hate me. If I can avoid using a card, or avoid taking my phone, I don't.

In such a short time we've gotten to total coverage of every act by every single person in America in very few databases, trivial to coordinate. I don't need anybody to know I always buy a bottle of water on the way to my board game night on Thursdays from one of the stores down the same road between the park I kill time at and the house where we have it. But then there's all these phones coming together, in that house, every Thursday. Even if I don't take my phone, even if I don't buy the water, they'll see I used my transit card to take the train to the park rather than to my apartment. It's horrific when I think about it.

They know when I turn on my computer, they know when I turn off my computer, they know when I turn on my television, they know when I turn off my television. With "smart" homes, they'll know when I turn my lights on and off, they'll know how often I cook, be able to guess what I'm cooking by looking at my shopping list. I don't have control of my phone, and it has a microphone in it. My car reports its location to the manufacturer. None of this is of any benefit to me.

The only barrier to total control is manpower, and historically the manpower has been easy enough to find. I'm looking to move counterclockwise on this circle. From 8:00 to midnight we're probably on the verge of getting questioned by the cops if they can see you but can't ping you. Let me go back in time.
