Russian UnionPay Cards in Korea: how it works in South Korea — first-hand

While some users report successful transactions in various stores (e.g., Olive Young, Daiso, clothing stores), many experience difficulties or outright rejections. Cards are generally more reliable for ATM cash withdrawals. The success rate may vary depending on the specific bank and merchant. It is advisable to have alternative payment methods, such as USD cash for exchange or a local Korean card.

Payment terminals sometimes prompt for a 6-digit code after the PIN, and card usage may become restricted after multiple attempts. ATM withdrawals might also fail. Customer support suggests resetting PIN via ATM balance inquiry, but this is not always effective. Workarounds mentioned include entering '00' after the PIN or using Yandex Browser.

While some terminals, like those for Wowpass top-ups, might accept them, transit systems (subway, bus, taxi) and some retail points may not. Payment success can be inconsistent across different merchants and payment systems. It is recommended to have alternative payment methods, such as cash or a local transit card, readily available.

Their functionality is primarily restricted to specific ATMs for cash withdrawals. Point-of-sale transactions are generally unreliable. Travelers should rely on alternative payment methods like international Visa or Mastercard, or carry sufficient South Korean Won (KRW) for transactions.

Among Russian banks, UnionPay cards are issued by several institutions; RSHB is easier to obtain, while ATB is reported to be more stable. Alternatively, acquiring a foreign bank card in countries like Kazakhstan or Uzbekistan is a viable option for international transactions.
