Banking’s best ‘boring’ innovation

When we talk about financial innovation, it’s usually about things like digital banking, crypto, or new ways of fundraising (like Regulation CF or ​Regulation A​).

But one “boring” technology has arguably had a bigger impact on financial services than any other:

The ATM.

The introduction of the ATM in 1967 fundamentally changed people’s relationship with banking.

For the first time ever, you didn’t need to be at the bank to do your banking. This revolutionary idea has now become so commonplace that it seems ancient (personally, I haven’t visited a physical bank branch in five years).

But automating “bank tellers” (and abstracting dollars away from their core physical location) was a very big deal.

In the wake of the ​Global Financial Crisis​, former Fed Chair ​​Paul Volcker​​ famously stated, “The ATM has been the only useful innovation in banking for the past 20 years.” Image: ​​Harvard Ethics​ via Flickr

Who actually invented the ATM?

It’s controversial.

The most popular narrative is that British engineer John Shepherd-Barron conceived the idea in a eureka moment —allegedly while ​pondering chocolate vending machines​ in the bathtub.

John Shepherd-Barron stands proudly with his invention. Ever wonder why bank PINs are only 4 digits long? Apparently, John’s wife ​couldn’t easily remember​ a string of digits longer than 4. Thus, ​the standard PIN length was set​.

While the bathtub episode is a nice anecdote, it’s not the whole story.

The “true” inventor of the ATM is hotly contested. ​Entire websites​ are dedicated to the debate, and ​PR battles​ between competing inventors.

In reality, it wasn’t invented by a single person. The modern ATM is the offspring of a few related projects:

The ATM’s form factor hasn’t actually changed all that much in the past 50+ years – although screen technology has certainly improved. Images: Left via ​​LIBN​​, Right via ​​Infrogmation​ via Wikipedia ​

What is agreed upon, however, is that John Shepherd-Barron (the British guy above) led the team that ​installed the first modern ATM​ at a Barclays branch in London in 1967.

The introduction of the world’s first ATM was a public event, with crowds invited to watch. Only certain bank customers could use it, though, and withdrawals were limited to £10 (about $230 today). ​Image: ​Barclays​

Regardless of who created it first, the ATM had absurd growth during the 80s and 90s.

How did ATMs spread so quickly?

At the beginning of the 1970s, there were about 1,500 ATMs deployed globally.

This was a quick ascent for such a new technology, but nothing like the ​growth bomb​ that was about to hit:

From 1970 to 2000, ATMs had a CAGR of 24.2% (for 30 years)

It’s easy to point to convenience as to why ATMs became so ubiquitous so quickly. But their spread was also simply because the world got richer.

As a country develops, ​the use of cash tends to fall​. Critically, wage payments start to be made not by cash, but by via bank account transfer.

This means in order to get their hands on cash, people need to either visit a bank, or an ATM.

Paradoxically, a country that relies less on cash needs more ATMs.

Wealthier countries have more ATMs – not because cash is more important, but because ATMs become one of the only ways to access cash when wages are paid electronically. ​Chart: ​Our World in Data​

Of course, there are limits to this dynamic.

In a society so rich that it abandons cash altogether, ATMs start to lose value.

This is why high-income countries have seen a noticeable decline in the number of ATMs in the past few years. (We’ll discuss the idea of cashless societies in more depth later on.)

How do ATMs actually work?

On the surface, an ATM withdrawal seems pretty simple. Insert your card, enter your banking info, withdraw cash, and let the bank deduct it from your account.

But this apparent simplicity hides a world of complexity underneath. After all, our simple model cannot answer a range of crucial questions:

  • How is it possible that you can withdraw cash from the ATM of a bank that you don’t have an account with — including foreign banks when you’re traveling abroad?
  • For that matter, many ATMs aren’t owned by banks at all. How do independently owned ATMs get access to your bank account?
  • Why do some ATMs have a surcharge for withdrawals and some don’t? And how do surcharge-free ATMs make money?

Allpoint (which isn’t even a bank) has a network of surcharge-free ATMs in the US. How do they stay in business? (Hint: Surcharges aren’t the only kind of ATM fees.) ​Image: ​NCR Atleos​

To answer these questions, we need to dig into the behind-the-scenes financial infrastructure that makes it all possible.

In the process, we’ll see how what was simply a convenient service offered by your bank became a lucrative business in its own right.

EFT networks are the key to everything

ATMs are only made possible by EFT networks (Electronic Funds Transfer). These crucial networks link banks together in order to verify and authenticate transactions.

Let’s say you have an account with “Alpha Bank,” but want to withdraw cash from an ATM operated by “Delta Bank.”

In this case, Alpha Bank simply needs to connect to an EFT network in common with Delta Bank to verify that you have enough money available to execute the transaction.

If Delta Bank signs off, you’re good to go. Alpha Bank fronts you the cash, and the two banks settle up later.

But the situation gets more complicated when you want to withdraw cash from an ATM run by a “no-name” ATM, or what’s known as an ​Independent ATM Deployer​ (IAD).

Since non-bank operators can’t use EFT networks on their own. this case, the IAD needs to get sponsored by a big bank to access EFT networks.

If you’re an HSBC customer, there’s a big difference between getting money from a Bank of America ATM, and a “no-name” IAD ATM. Interestingly, you can find real sponsorship agreements on the SEC’s website, like ​this agreement​ between American State Bank and ​Global Cash Access​.

From here, the process works much the same as before: The sponsor bank contacts Delta Bank to verify sufficient funds for the withdrawal. But this time, the IAD fronts you the money.

When you use an IAD ATM, the request flows through the sponsor, through the EFT network, and finally to your bank (or more technically, “card-issuing financial institution”) which either authorizes or declines the request.​ Image: ​GAO​

Basically, EFT networks provide the common language for the world’s ATMs to communicate. Banks know how to speak that language, but IADs need a translator (a sponsor bank).

And just like the real world, there are both international languages and regional dialects:

Cirrus and Plus are two of the two largest international ATM networks. Between them, they cover ​millions of ATMs​.

If your debit card has a Mastercard or Visa logo (which most do), then congratulations: You can seamlessly withdraw cash from almost anywhere in the world.

Mastercard’s Cirrus EFT and Visa’s Plus EFT networks are some of the most critical financial entities you’ve probably never heard of.

In days gone by, networks were satisfied just being networks; sitting in the background, facilitating transactions, and earning fees for doing so.

But lately, networks have stepped out of the background, helping spark the rise of fee-free ATMs.

Money for nothing: The rise of surcharge-free ATMs

Here’s the thing about ATM fees: users hate paying them.

Almost ​80% of people​ will do anything they can to avoid paying ATM fees — a feeling that has likely intensified as fees have continued to rise.

Average total ATM fees in the US have been rising for a while now, fueling frustration. ​Since customers hate paying ATM fees, offering free ATM access is a competitive advantage for banks. Chart: ​Bankrate​

Generally speaking, banks offer ATMs to their account holders as a perk, while IADs offer ATMs as a business.

That’s why you don’t get a fee for using your own bank’s ATM, but you’ll probably get smacked with one for using the unbranded ATM at your local bar.

What’s an ATM alliance?

But here’s the problem: While rolling out a nationwide fleet of bank-owned ATMs might be possible for JPMorgan Chase, it’s way too expensive for smaller banks.

The solution? Get a bunch of banks to form an ATM alliance, where account holders at all the participating banks can use the alliance’s ATMs for free.

And who better to fill the alliance role than the EFT networks themselves, which already link the banks together in the background!

  • ​Allpoint​ used to be just a network, but they now own or operate 43,000 fee-free ATMs in the US (with about 2,000 member banks).
  • Similarly, ​Moneypass​ was originally formed from two regional networks, and now has about 40,000 fee-free ATMs in the US (and about 1,000 member banks).

In total, Moneypass and Allpoint account for about 16% of all ATMs in the US.

Instead of charging users directly, these companies get paid by the banks themselves (usually on a per-transaction basis).

Still, there are plenty of fee-charging ATMs around the world. And, if you get access to a good location, they can potentially be a lucrative business opportunity.
