You’re standing in front of a flickering vending machine at 11:30 PM. You just need a single ride. No, you don't want to download an app that requires a 14-character password. No, you don't want to register a plastic card that costs $5 just to own. You just want a one time payment metro ticket so you can get home.
It's getting harder.
Transit agencies from New York to London are obsessed with "frictionless" travel. To them, that means getting rid of paper tickets and tokens entirely. But for the occasional traveler or the tourist who just landed, the death of the single-use ticket feels like a massive headache.
The Slow Death of the Magnetic Stripe
Honestly, the technology is ancient. If you've ever had a MetroCard fail because it was too close to your phone’s magnet, you know the frustration. Transit systems are bleeding money maintaining these mechanical dispensers. New York’s MTA, for instance, has been phasing out the physical MetroCard in favor of OMNY.
OMNY is basically a system where your phone or contactless credit card is the ticket.
But what if you don't have a contactless card? Or what if you're a privacy nut who doesn't want the city tracking every turnstile you pass through? That's where the one time payment metro dilemma hits a wall.
Agencies argue that moving away from physical tickets saves millions in printing and maintenance. They aren't wrong. Paper tickets jam machines. They litter the tracks. They require specialized ink and magnetic encoding that costs a fortune to scale. In London, the Oyster card was the king for a decade, but now, even the Oyster is being overshadowed by "Pay As You Go" (PAYG) using standard bank cards.

Where Can You Still Just Pay Once?
It depends on where you are.
In Paris, the RATP finally started moving away from the iconic "Ticket t+" cardboard strips. They introduced the Navigo Easy, which is a rechargeable card, but it’s not exactly a "one and done" solution. You still have to buy the card first.
Tokyo is different. You can still walk up to a machine in Shinjuku, look at a massive map that looks like a circuit board, and buy a small paper ticket for a specific fare. It’s tactile. It works. But even there, Suica and Pasmo—the digital equivalents—are the preferred method for anyone who values their sanity.
If you are looking for a one time payment metro experience in the US:
- Washington D.C.: The SmarTrip card is mandatory. You can buy a "Limited Use" paper card in some scenarios, but the system is designed to punish you for it with surcharges.
- Chicago: The Ventra system offers a single-ride paper ticket, but it costs more than the standard fare. They basically tax you for not having the permanent card.
- Los Angeles: The TAP system is almost entirely digital or plastic now.
The "Hidden Tax" on Occasional Riders
Let’s talk about the math.
When a city moves to a digital-first system, they often implement "fare capping." This is actually great for locals. If you spend $5, the system stops charging you for the rest of the day. But for the person looking for a one time payment metro option, there is no cap. You pay the maximum price for every single leg of your journey.

There's also the "unbanked" issue. About 5.9 million households in the U.S. don't have a traditional bank account. If a metro system removes the cash-to-paper ticket option, those people are effectively locked out of public transit. This is why cities like San Francisco and New York still keep some form of physical card vending machine, even if they'd rather rip them all out.
Why Contactless is Winning (And Why You Might Hate It)
The convenience is undeniable. You tap your Apple Watch. The gate opens. You move on.
But here’s the rub: many international travelers find that their home-country cards don't always play nice with foreign readers. I’ve seen people at the Heathrow Express gates nearly in tears because their mid-western credit card wouldn't trigger the NFC sensor.
In those moments, a one time payment metro ticket is a lifesaver. It’s a physical guarantee.
Technology experts like those at Cubic Transportation Systems—the guys who build these gates—know that the "closed-loop" system (where the transit agency issues its own currency) is safer for the agency. It means they hold your money. When you buy a $20 card and only use $18, that $2 stays in their bank account. Multiplied by millions of riders, that "breakage" is a massive revenue stream.
Practical Hacks for the Modern Transit User
Since the world is moving away from the single-payment model, you have to adapt.

- Check for "Virtual" Transit Cards: Don't wait until you're at the turnstile. In cities like Tokyo or Hong Kong, you can add a transit card directly to your Apple Wallet or Google Pay without buying a physical card.
- Look for the "Limited Use" Machine: Some stations have two types of machines. One sells the fancy plastic cards. The smaller, older-looking one often still sells the one time payment metro paper tickets.
- The Pharmacy Trick: In many US cities, you can't buy a single-ride ticket at the station, but you can buy a pre-loaded single-use card at a nearby CVS or Walgreens.
- Validating is Key: In Europe (think Berlin or Prague), buying the ticket is only half the battle. If you don't stick it in the little yellow or orange box to get it time-stamped, you’re technically riding dirty. The fines are aggressive.
The Future of the Single Ride
We are moving toward a world where your face or your palm might be your ticket. China is already testing biometric "smile to pay" systems in several metro hubs. It’s efficient. It’s also incredibly creepy for anyone who values privacy.
For now, the one time payment metro is in a weird state of limbo. It exists as a backup for the tech-illiterate or the transient, but agencies are making it intentionally inconvenient to use. They want you on the app. They want your data.
If you're traveling soon, don't assume you can just "pay as you go." Spend five minutes on the transit agency's website before you leave the airport. Look specifically for "Fare Media" or "Ticketing Options."
Actions You Can Take Right Now
Stop looking for the coin slot. It's probably blocked off.
Instead, open your phone's wallet app and search for the city you're in. Many major metros now allow you to generate a digital card instantly. If you absolutely must use cash, head to a staffed booth—if you can find one. Most systems are phasing out human tellers too.
Finally, if you're in a city that still uses tokens (they're rare, but some smaller systems in South America or Eastern Europe still love them), buy a handful at once. The line for the one time payment metro machine will always be longest when you're late for your train.
The era of the simple paper ticket is ending. It's frustrating, it's a bit cold, and it's definitely less romantic than a pocket full of tokens. But the rail is still the fastest way across town. Just make sure you've got your NFC turned on before you hit the gate.
