Turns out you can tell exactly who a product is for just by watching who gets approached — and who doesn't.
I had a reason to stop by the Lotte Mart at Seoul Station, and right near the entrance there was a small promotional booth working through a crowd of tourists — entirely in Chinese. I didn't think much of it in the moment, but it turned out to be a good entry point into everything that's changed in Seoul's transit card scene lately. More on that booth further down.

That card turns out to be CHECK iN SEOUL, and it's one of several things that have changed in Seoul's transit card landscape recently — starting with a major restructuring of the Climate Card that took effect on September 1st. If you read my earlier post on T-Money, the Tmoney Travel Card, and the Climate Card, you already know the basics, and that post is still accurate for the fundamentals. But a few new cards have shown up since then, and the Climate Card itself just went through a genuine overhaul. So this is the update post: what changed, what's new, and what actually matters if you're visiting rather than living here.
Seoul's Climate Card Lost Its 30-Day Pass — Here's What Didn't Change
If you've been researching the Climate Card (기후동행카드) and you're now running into conflicting information, that's because the ground genuinely shifted under it. As of September 1, 2026, the old 30-day Climate Card — the one long-term residents used as an unlimited monthly transit pass — was discontinued. It's been folded into a new nationwide system called 모두의카드 (Modu Card, roughly "everyone's card"), which runs on the government's K-패스 (K-Pass) infrastructure instead of being a Seoul-only product.
The timeline, if you're trying to make sense of it: the prepaid version of the old Climate Card could be topped up for the last time on July 31st, and it kept working through late September. The postpaid, credit-card-linked version kept its discount benefits through the end of September. After those dates, both versions stop functioning as the Climate Card — they're just regular transit cards or credit cards now, with no unlimited pass attached. Seoul is also running a swap event at twelve subway stations through early October where holders of the old physical Climate Card can trade it in, free of charge, for a physical Climate Pass card under the new system.
None of this affects short-term visitors, and that's honestly the most important line in this section. The tourist-facing short-term Climate Card passes — 1-day, 2-day, 3-day, 5-day, and 7-day — were never part of the 30-day system, and they continue exactly as before. If you're in Seoul for under a week and planning four or more subway and bus rides a day, the short-term Climate Card is still the same good deal it was when I wrote the original post.
What has genuinely improved for tourists is how you pay for it. Since mid-March 2026, station ticket machines across Seoul's Lines 1–8 started accepting foreign-issued Visa and Mastercard credit and debit cards directly, along with Kakao Pay and Naver Pay. Before that update, visitors without Korean cash on hand would genuinely get stuck at the machine. There's a processing fee of a few percent for using an overseas card, which isn't nothing, but it beats hunting for a currency exchange counter while your train pulls away.
The New "Modu Card" Is Everywhere Right Now — But It's Not Built for You
If you've seen headlines or ads about 모두의카드 this month, I understand why it looks appealing — it genuinely is a strong upgrade for people who live here. Instead of being limited to Seoul, it works across roughly 198 regions nationwide, folds in the government's K-Pass fare-refund structure — up to around 30% back for users aged 19 to 39, with smaller refunds for other age groups — and Seoul-specific perks were applied automatically to existing K-Pass users starting September 1st, with no extra steps required on their end.
One naming note, since it caused genuine confusion even here: Seoul originally announced this rollout under the name "기후동행카드 플러스" (Climate Card Plus). After a month of back-and-forth with the national transportation authority over branding, that name was dropped, and what actually launched on September 1st is officially called 모두의카드(기후동행패스) — Modu Card, with "Climate Companion Pass" as its Seoul-specific branch. If you come across "Climate Card Plus" anywhere, it's referring to the same thing, just under a name that never made it to launch.
Here's the part that answers the question I know a lot of readers will have after seeing this everywhere: Modu Card registration runs through Korea's resident registration system. For Korean citizens, that means a 주민등록번호 (resident registration number). K-Pass–style programs have required participants to be registered residents of a participating region, which in practice means the card is tied to having an address on Korean resident registration — something a short-term tourist simply doesn't have. Without that registration, there's nothing to attach the card's refund and unlimited-ride mechanics to, even if you're technically able to hold a Korean-issued card in your hand.
I'll admit this is a little confusing, because "Modu" literally means "everyone," and the marketing push right now is loud — you'll see it on subway posters, hear about it from Korean friends, and possibly get asked by station staff if you've switched over. If you're just visiting, you can safely ignore all of that. It's a great deal, just not one you're eligible for yet.
M-Pass: The Original Foreigner-Only Transit Card
Before any of the newer all-in-one cards existed, there was M-Pass (엠패스), and it's still around, quietly doing its job. It's issued exclusively to foreign tourists — Tmoney's operator built it specifically so visitors could get something close to unlimited transit access without needing to navigate the resident-only Climate Card system at all.
M-Pass works a little differently from a flat unlimited pass: it caps you at 20 rides per day, covering the Seoul metropolitan subway, the regular AREX airport train (not the express version), and Seoul city buses including night buses. There's also a Jeju version that works the same way on the island. It's sold in daily increments from one to seven days, with pricing running from around ₩15,000 for a single day up to roughly ₩64,500 for a week — cash only, in Korean won, with no foreign card option at purchase.
You pick it up and return it at T-money Town near Seoul Station, Exit 10. There's a small deposit built into the price, and you get most of it back — minus a modest service fee — when you return the card at the end of your trip, along with any leftover balance. It's a bit more old-school than the newer app-driven cards, with no mobile registration and no balance-splitting to think about. If you just want a card that does unlimited-ish rides and nothing else, it's still a clean, uncomplicated option.
WOWPASS, CHECK iN SEOUL, and NAMANE: Three More Cards Worth Knowing
This is where things have gotten more crowded. WOWPASS and CHECK iN SEOUL are both foreigner-exclusive prepaid cards that try to do three jobs at once — transit, everyday payment, and currency exchange — instead of making you carry a separate transit card and payment card. There's a third card, NAMANE, that overlaps with these two but isn't actually foreigner-only — more on that below.
WOWPASS has been around longer and runs on the actual Tmoney network, meaning it has full nationwide transit compatibility — subways and buses anywhere Tmoney works, which is essentially everywhere in the country. It's issued through more than 430 unmanned kiosks at airports, subway stations, and hotels, and you top it up at those kiosks using foreign cash, a foreign card, or an e-wallet. These days you can also top up your Tmoney transit balance directly inside the app, so a kiosk run isn't strictly necessary once you're set up. It's not a fringe product, either — WOWPASS reports more than 3.36 million cumulative users on its official site, and the user stories I came across while researching this held up under scrutiny: a lost card frozen instantly through the app, a suitcase left in a taxi tracked down through the payment history, a store's billing mistake refunded through WOWPASS's own customer service rather than the traveler having to sort it out in a language they didn't speak. It's also actively expanding — a new partnership with Tmoney GO means the app will soon handle taxi calls and intercity bus bookings as well, not just tap-and-ride transit.
CHECK iN SEOUL is the newer entrant, launched this year as a partnership between Lotte Card and LG Uplus — and it's the card behind that promotional booth I walked past. It runs on a transit network called eZL rather than Tmoney directly, carries a small issuance fee taken from your first top-up, and can be charged through the app using a foreign Visa, Mastercard, or JCB card, or with foreign cash at a kiosk. It also doubles as a mobile passport once you register your passport details in the app, which is a nice touch for identity checks at partner locations.
There's a third option worth knowing about too, and it's a bit different in spirit from the other two — starting with the fact that, unlike WOWPASS and CHECK iN SEOUL, it isn't actually exclusive to foreigners. NAMANE Card is a general Korean prepaid card, run by the fintech company i-aurora, that's long been used domestically for everyday things like phone bill autopay — it's just that the personalized design option is what makes it click for visitors. You design the card yourself at a kiosk: upload a photo of your favorite K-pop idol, a shot from your trip, or pick from pre-made character designs, no passport needed. The photo-customized "Full-Type" card runs about ₩10,000, though it's frequently discounted to around ₩9,000. It's printed on the spot at roughly 100 kiosks nationwide, open 24 hours, including at Incheon and Gimpo airports, Seoul and Busan stations, Myeongdong, and Hongdae. Beyond the novelty factor, the app handles the practical side — recharge anytime, top up your transit balance directly without a kiosk trip, send money to friends by scanning a QR code, withdraw cash at convenience stores, and lock the card remotely to protect your balance if you lose it.
There's actually one of these design kiosks inside Seoul Station itself — I've walked past it more than once. The first time I noticed it, I honestly wondered whether anyone actually used the thing. But watching for a bit, people genuinely do stop and make one.
I haven't made one myself, but now that I've looked into what it actually does, I get the appeal — and it's on my list to try next time I'm passing through.
This actually connects to something I went through myself. I once tried to find a nicely designed T-money card for my kids — Tmoney's own site does have some good-looking ones — but those special-design cards aren't sold at every convenience store. You have to track down the specific branch that carries them, which is a lot more effort than it should be. If I'd known about NAMANE back then, with kiosks right there ready to print whatever design you want on the spot, I probably would've gotten them made for my kids instead — they're both into K-pop, and a card with their favorite idol on it would've been an easy win.
One caveat worth flagging: acceptance for everyday store payments is spottier than the marketing suggests — plenty of restaurants and most accommodations don't take it, so treat it as a transit card with a nice bonus rather than a full WOWPASS or CHECK iN SEOUL replacement. NAMANE also sells a separate K-POP Pass, an unlimited transit pass rather than a payment card, in 4-day and 6-day versions that cover subways, city buses, GTX, and the general-speed airport train — though not the express AREX, airport limousine buses, reserved-seat coaches, or a handful of rural counties.
| Feature | WOWPASS | CHECK iN SEOUL |
|---|---|---|
| Transit network | Tmoney (fully nationwide) | eZL (nationwide, occasional gaps in remote areas) |
| Kiosk locations | 430+ (airports, stations, hotels) | Airports, Myeongdong, major hubs |
| Track record | 3.36M+ cumulative users since launch | Launched in 2026, still expanding |
| Standout perks | Cashback at Olive Young and convenience stores, taxi/bus booking via Tmoney GO | Lotte World, Lotte Mart, and duty-free discounts, LG Uplus eSIM tie-in |
If your trip is heavy on café-hopping, convenience store runs, and general shopping, WOWPASS's longer track record and its widening feature set probably make it the safer bet. If you're planning to hit Lotte World or do serious duty-free shopping — or you're already getting an eSIM through LG Uplus anyway — CHECK iN SEOUL's perks line up more directly with that itinerary, just know it's newer and still building out its kiosk network.
What I Saw at Lotte Mart
Let me go back to that booth, because it stuck with me more than I expected. Two staff members, both speaking fluent Chinese, working through a small crowd of tourists near the Lotte Mart entrance — flyers, a QR code, the whole setup. And I just wasn't part of it. I slowed down out of curiosity, half thought about asking what they were promoting, and then kept walking, because it was obvious the booth wasn't aimed at me. Nobody made eye contact. Nobody handed me a flyer.
At first I assumed it was random — maybe they were mid-conversation with someone else when I passed. But watching for another minute, it was clearly deliberate. They were reading the crowd, and I read as local. Which, obviously, I am — but it was a strange, small moment of realizing that a card built for "foreigners" is invisible to me by design, even standing three feet away from the booth. I wasn't being excluded so much as correctly filtered out. It's such a minor thing, but it says something about how targeted these products have become. A few years ago, foreigner-exclusive transit cards barely existed. Now there's enough of a market that companies are running language-specific street promotions for one particular card, at one particular mart entrance, clearly reading which tourists to approach.
It also made me think about how much of this infrastructure most Koreans, myself included, will simply never touch. I've never used M-Pass, WOWPASS, or CHECK iN SEOUL, and I probably never will — not because they're bad products, but because I already have a bank card that taps at every gate in the country. The entire category exists on a parallel track, built and marketed exclusively for people passing through. Which, in a roundabout way, is exactly why a post like this is useful — this stuff isn't something you'd stumble onto by watching how locals get around, because locals were never the intended audience.
So Which Card Should You Actually Get?
Pulling this all together, here's how I'd think about it depending on your situation.
If you're in Seoul for under a week and riding transit heavily, the short-term Climate Card is still your best value, and it's genuinely easier to buy now with foreign card acceptance at station kiosks. Nothing changed here except that it got more convenient.
If you want a no-frills, close-to-unlimited option and don't mind paying cash and picking the card up in person, M-Pass at Seoul Station still works exactly as it always has.
If your trip includes a lot of shopping — convenience stores, cafés, everyday spending — WOWPASS's track record and its growing feature set will probably serve you better over the course of a trip than a transit pass alone.
If Lotte World, duty-free shopping, or an LG Uplus eSIM are already on your itinerary, CHECK iN SEOUL's perks are worth the small issuance fee — just remember to move funds into the transit balance before you tap the gate.
If you're a K-pop fan and the idea of a transit card with your bias's face on it sounds more appealing than a plain gray one, NAMANE Card is worth the detour to a kiosk — just keep a WOWPASS or a regular T-money card as backup for places that don't take it.
And if you saw 모두의카드 trending and wondered whether you were missing out on something, you're not. It's a genuinely good upgrade, just one built for people who live here rather than people visiting. Save yourself the confusion and skip it unless you end up staying long enough to register as a resident.
