A Long-Standing Travel Struggle
For many years, one would commonly see everyone at Seoul’s busy subway stations — foreign tourists who were struggling at the ticket kiosks, without knowing why their shiny international Visa cards wouldn’t work. Seoul prides itself on being a digital capital, however, visiting the city did not always ensure an easy experience getting around.
Every traveler was required to buy a t-money card, typically with cash, prior to getting on a bus or train. It was not only confusing but also took considerably longer if the traveler did not have Korean won. Even at modern subway stations, kiosks didn’t accept foreign credit cards, leaving many to queue at convenience stores to top up their cards manually.
But the good news? That frustrating era is finally ending. The Seoul foreign credit card payment system is here to make urban travel truly global.
The Problem: A Smart City With an Old System
While Seoul is known worldwide for its high-speed internet, smart roads, and digital lifestyle, its public transport payment method was surprisingly outdated. Korea’s transit network has long relied on T-money and PayOn systems, which work only with local bank-issued cards and prepaid balances.
Foreign tourists couldn’t tap their own cards directly because Korea’s system wasn’t compatible with global networks like Visa or Mastercard. Even tech-savvy travelers using Apple Pay or Google Pay found themselves stuck.
According to the Seoul Metropolitan Government, over 16.3 million foreign visitors entered Korea in 2024, with numbers expected to surpass 20 million in 2025. Yet most still relied on cash to recharge their transit cards — an inconvenience that felt out of place in one of the world’s smartest cities.
Many tourists even took to online forums to express frustration. A visitor to Korea from the United Kingdom shared that “I could use my card anywhere I went in Seoul except the subway — that’s ironic considering it’s a city built on technology! ”
The Big Fix – Seoul’s Open-Loop Payment Revolution
In an effort to change this, in October 2025 the Seoul Metropolitan Government unveiled its ambitious plan to roll out an open-loop payment system across the public transport network by 2030.
This means visitors will be able to tap their foreign-issued credit or debit cards — whether physical or mobile — directly at subway gates or bus terminals. No more separate T-money cards, no cash recharges, and no language barriers at kiosks.
The new payment structure will operate on the EMV standard (Europay, Mastercard, and Visa), which is already used in global cities such as London, Singapore, and Sydney. Once implemented, Seoul’s system will become one of the most advanced in Asia.
According to city officials, the first step begins this year. By the end of 2025, foreign credit cards will be accepted at 25 newly designed subway kiosks for purchasing and recharging transit cards. In total, 440 kiosks will be installed across major lines.
For Apple users, the T-money app will soon support Apple Pay top-ups using foreign cards, while Android users can already recharge through the Korea Tour Card app.
How It Will Work
By 2026, EMV modules will be installed on all major bus terminals.
By 2027, subway gates on Lines 1–8 will be upgraded.
Between 2028 and 2030, the system will expand to smaller “maeul” (village) buses, private rail lines, and the greater metropolitan network.
Once fully launched, tourists can simply board any bus or train, tap their Visa, Mastercard, or compatible phone wallet, and the fare will be automatically deducted in their home currency — just like in London’s Tube or Singapore’s MRT.
The entire upgrade is expected to cost around 50 billion won ($35.2 million), a major investment in tourist convenience and smart infrastructure.
What It Means for Tourists (and Locals Too)
This change will drastically improve how foreign travelers experience Seoul. No more hunting for kiosks, carrying coins, or worrying about language settings.
Before:
- Needed T-money or Korea Tour Card
- Cash-only recharge at stores
- No direct credit card payments
After:
- Tap-and-go with Visa/Mastercard
- Recharge through Apple Pay/Google Pay
- Seamless transfers between bus and subway
For locals, the system also offers flexibility. Koreans traveling abroad can use their cards in countries with EMV-based transport networks — creating a truly connected global payment ecosystem.
Yeo Jang-kwon, head of Seoul’s Transportation Office, emphasized in a statement, “Seoul is now a global tourist city, and its transit system should meet international standards. The open-loop system will improve convenience for foreign visitors and reinforce our image as a smart city.”
Seoul Joins the Global League
Seoul’s transformation aligns it with other forward-thinking cities.
- London introduced contactless transit payments in 2012, integrating bank cards and smartphones.
- Singapore followed in 2019, and Sydney soon after.
- Hong Kong is currently transitioning from its Octopus card to an EMV-supported network.
By adopting the Seoul foreign credit card payment system, the Korean capital will join this elite group — but with even wider scope, combining the PayOn and EMV systems for maximum flexibility.
Smart City Seoul 2030 — The Bigger Picture
This shift is not just about moving, but rather part of a much larger view for Smart Seoul 2030. The city plans to integrate mobility, payments, and tourism into a single digital ecosystem.
With projects like AI powered traffic and transport control, electric “eco-buses,” and real-time tourist information assistance apps, Seoul aims towards becoming the world’s most connected urban travel hub.
This upgrade at a global standard shows you Seoul is not merely keeping up with the trends, it is setting them. For a city that combines tradition with technology, this transportation system elegantly connects the two worlds.
