WeChat Pay on Seoul Subway 2026: What You Can and Can't Buy With It

Since March 17, Seoul Metro has let riders buy or top up transit cards with foreign-issued credit cards and e-wallets at new kiosks on Lines 1–8. An analysis of the first month after launch (March 17–April 17) found that an average of 9,158 people a day paid about 70 million won total via foreign cards and e-wallets; by payment type, VISA led with a daily average of 3,788 transactions, and among e-wallets, WeChat Pay's daily average of 2,069 transactions outpaced domestic e-wallets' 628. By station, usage was highest at Seoul Station (5.26 million won/961 transactions daily on average), followed by Hongik Univ. Station (4.99 million won/880) and Myeongdong Station (2.82 million won/893). However, what you can buy with foreign cards or e-wallets is limited to single-journey tickets, the Climate Card, and short-term (1/2/3/5/7-day) passes — topping up a regular T-money card isn't possible this way. Whether Alipay is supported isn't mentioned in this source, so that remains unconfirmed.
