Summary: If you’ve ever landed at an airport or wandered through a busy shopping mall abroad, you’ve probably wondered: can I just swap my small stash of euros—say, 16 euros—for US dollars at a self-service machine, or am I stuck queuing at a staffed exchange? This article shares my personal experience, breaks down how these machines work, and dives into international standards and regulations. Plus, I’ll sprinkle in a few mishaps (because who hasn’t fumbled with a currency machine?) and give you a clear, practical answer.
The main issue here: you’ve got a relatively small amount of euros—maybe left over from a trip—and you want to convert them to US dollars. Do you need to line up at a staffed foreign exchange booth, or can you use a self-service (automated) currency exchange machine? And if you can use a machine, is it worth it? Are there any rules or catches you need to know?
Based on my own experience bouncing between New York, Frankfurt, and Amsterdam airports (and yes, sometimes just hunting for a way to get rid of annoying leftover coins), here’s how it typically goes. For the sake of detail, I’ll use the Travelex self-service machine at JFK International as an example.
Not every airport or city center has these. In my case, JFK has Travelex and some smaller machines, while Schiphol in Amsterdam has GWK Travelex self-service kiosks right by the arrivals hall. These machines are usually near the main exit, and look a bit like oversized ATMs. Here’s what one looked like last time I used it:
Here’s where things get tricky. Most self-service machines do allow you to exchange small amounts of cash, but they often set minimums (usually around 10-20 euros) and maximums (sometimes up to 5000 euros or more). With 16 euros, you’re just inside the typical minimum. But—and this is important—some machines only take bills, not coins. So if your 16 euros is all coins, you’re out of luck.
In my experience at JFK, the Travelex machine accepted euro notes starting at 5 euros, but no coins. At Schiphol, it was similar. I tried feeding in a 5 and a 10 euro note—worked fine, but when I tried a handful of coins, I got an error and a polite on-screen message: “Coins not accepted.” So, double-check what you have.
The process itself is pretty straightforward:
I once tried this at Frankfurt airport with 20 euros, and the screen actually asked if I wanted “small denomination bills” for my payout. Nice touch—sometimes you need singles for tips.
Pro tip: Some machines only operate during airport hours, and may “run out” of cash for certain currencies, so don’t be surprised if you get a message like “USD currently unavailable.”
If you can’t find a self-service machine—or your bills are crumpled, torn, or in coins—your next best bet is a staffed currency exchange booth. These are everywhere in major airports, big malls, and sometimes even train stations. Staffed counters almost always have higher fees, but they’ll accept both notes and coins (sometimes with a coin handling fee).
On one trip, I tried exchanging just 10 euros in coins at a staffed Travelex counter at Heathrow. The teller counted every coin, double-checked the total, and after a 3 GBP coin handling fee (yikes), I got about $8.25 in USD. Not great for small amounts, but at least it worked.
You might wonder if there’s a global rulebook for these machines. Turns out, there isn’t a single global law, but there are some international standards and national regulations:
There is a huge difference between “verified trade” standards in different countries. Here’s a quick comparison:
Country | Verified Trade Standard | Legal Basis | Enforcement Agency |
---|---|---|---|
USA | FinCEN AML Registration | Bank Secrecy Act | FinCEN/Treasury |
EU | 4th AML Directive | EU Parliament Directive 2015/849 | National Financial Supervisors |
Japan | Official Money Changer Permit | Act on Prevention of Transfer of Criminal Proceeds | FSA (Financial Services Agency) |
Let’s imagine two friends—Anna from Germany and Mike from the US—are in Tokyo and want to exchange 16 euros for USD at a self-service machine. Anna tries the machine, but it spits out a warning: “Transaction exceeds local verification threshold.” Turns out, Japan’s machines require ID for anything over 10,000 yen (about 65 euros), but for 16 euros, no ID needed. Later, Mike tries the same transaction at a US airport and gets his USD instantly, no questions asked. But try doing the same in a smaller EU city? You might need to show a passport, even for small amounts, depending on the operator.
Expert take: As pointed out by currency technology expert Dr. Sandra Lee in her 2023 industry review, “Automated machines are designed for convenience, but compliance with anti-money laundering rules means they sometimes refuse legitimate small transactions, especially if the machine’s cash supply is low or its risk scoring flags an issue.” (Finextra, 2023)
I’ve probably used a dozen of these machines over the last five years. Most of the time, exchanging something like 16 euros to USD is quick and painless—but not always. Once in Vienna, I tried to exchange 15 euros and the machine said “Amount too low—please insert at least 20 euros.” Another time, at Newark airport, I accidentally fed in a torn 10 euro note, and it was instantly rejected (and I had to chase down a staff member to get it back). My advice: always check the minimum/maximum limits, and make sure your bills are in good condition.
One thing that consistently annoys me: the exchange rates. Machines often have worse rates than online bank transfers or card payments. If you’re only exchanging a small sum like 16 euros, you might lose $2-3 to fees and poor rates. Still, sometimes you just want cash, and the machine is easier than waiting at a counter.
To sum up: Yes, you can usually exchange 16 euros to USD at self-service machines—as long as you’re using bills (not coins), the machine is working, and you’re above the minimum threshold. You don’t always need a staffed exchange, unless you have coins or very small bills, or if the machine is out of cash. Check the fees and rates first; for such a small sum, the convenience might outweigh the cost, but it’s rarely the best value.
If you’re traveling, my advice is to use up your small euro bills before you leave the eurozone. But if you’re stuck with 16 euros in bills, look for a self-service machine at your destination airport. And always keep your receipts! If something goes wrong, having proof of the transaction is a lifesaver.

Next steps? If you’re planning a trip, scout out the airport’s website in advance—many list their available currency services. And if you’re stuck, ask an airport info desk. Don’t be afraid to try the machines, but expect the occasional hiccup!
