How to Use Mobile Payment Apps in Korea – A Complete Guide for Foreigners

※ This article is based on official information as of August 21, 2025.

Summary at a Glance

South Korea is one of the most digitally advanced countries in the world, and nowhere is this more visible than in its mobile payment apps in Korea. From buying coffee at a convenience store to paying subway fares or splitting the dinner bill, Koreans rely on mobile payment platforms like KakaoPay, Naver Pay, Toss, Samsung Pay, and Payco every single day. For foreigners, understanding how these apps work is not just a convenience—it’s essential for navigating daily life.

Unlike in some countries where credit or debit cards still dominate, Korea has embraced cashless and contactless payments faster than almost anywhere else. Many cafés, taxis, and even small street vendors now prefer mobile payments. However, foreigners face unique hurdles: you typically need a Korean phone number, a local bank account, and an Alien Registration Card (ARC) to unlock full features.

This guide explains eligibility, step-by-step setup, regional differences, real-life case studies, cultural tips, and FAQs. By the end, you’ll not only understand the best mobile payment apps in Korea but also know exactly how to register and start using them—whether you’re a tourist, student, or long-term expat.
