South Korea's rapid shift toward a cashless economy is transforming how people pay, with cashless payments in South Korea now standard across digital and physical retail. In this dynamic landscape, Toss Pay is emerging as a trusted digital wallet, praised for its intuitive design, robust security measures, and seamless fit within South Korea's tech-savvy retail ecosystem.
Whether you're a global e-commerce lead eyeing market expansion, a fintech strategist tracking payment trends, or a digital entrepreneur navigating Korea's local preferences, this guide will help you understand why Toss Pay is becoming an essential part of South Korea's modern payment stack—and what it means for your business growth in the region.
The rise of digital payments in South Korea
The rise of digital payments in South Korea is driven by a hyper-connected population and one of the world's most advanced digital infrastructures. Several pivotal dynamics are shaping this transformation:
- Widespread smartphone adoption: With approximately 95% of South Koreans owning smartphones, mobile-centric payment solutions are not optional—they're foundational.
- Accelerating e-commerce sector: Online retail continues its double-digit ascent, expanding at an annual rate of 22.5%, with platforms like Coupang and Gmarket setting the pace.
- Decline of cash in favour of contactless: From QR code-based transactions to mobile wallets, modern payment methods in Korea are rapidly displacing conventional cash and card usage.
In step with these shifts, localised payment methods such as Toss Pay are fast becoming integral to participating—and succeeding—in South Korea's digital economy.
What is Toss Pay?
Toss Pay (aka Toss) is a dynamic digital payment service developed by Viva Republica, the fintech innovator behind the Toss super-app. Originally launched as a peer-to-peer money transfer tool, Toss has rapidly evolved into a multi-functional financial ecosystem encompassing banking, investment management, credit profiling, and digital payments. Toss Pay serves as the app's core payment interface, designed to simplify transactions across both online and physical retail environments—helping define the future of mobile wallets in South Korea.
As of 2024, Toss boasts over 19.1 million active users and commands a market valuation estimated between 15 and 20 trillion Korean won (approximately US$11–15 billion). Since February 2024, the platform has processed more than 30 trillion won (US$20 billion) in cash transfers—highlighting its expansive reach and trusted adoption.
Toss Pay equips users with a friction-light and feature-rich payment experience, including:
- Streamlined checkout journeys: Execute seamless, cashless transactions via QR and barcode payments—accepted at over 100,000 merchants domestically and across 42 international markets.

- Loyalty-driven value: Tap into Toss Points, exclusive coupons, and lifetime zero-fee transfers to maximise spend efficiency and drive ongoing engagement.
Why Toss Pay is gaining traction in South Korea
Embedded in a holistic financial ecosystem
Toss Pay functions as more than a standalone payment utility—it is tightly interwoven into the broader Toss platform, a multifunctional app that millions of South Koreans rely on for end-to-end financial management. This includes:
- Toss Bank: A fully digital bank that caters to both domestic users and foreign residents, offering streamlined onboarding and integrated financial services.
- Toss Securities: A unified trading interface enabling users to access diverse asset classes from a single account.
- Toss Mobile: A mobile virtual network operator (MVNO) offering competitively priced mobile plans embedded within the Toss ecosystem.
- Toss Place: An in-store payment and POS system for merchants, designed to centralise transaction management through Toss Pay's infrastructure.
Rapid, resilient payment execution
Users can seamlessly link their bank accounts or cards, removing the need for repeated data input. Toss Pay employs biometric validation and end-to-end encryption, ensuring robust security without sacrificing speed.
Engaging incentive architecture
Toss Pay incorporates cashback mechanisms and merchant-linked discounts, enhancing transactional value and fostering user retention. A standout example is the partnership with leading convenience chain CU, where users transact via barcode payments linked to their bank or credit card—and earn both Toss Points and CU rewards, redeemable across over 17,000 locations nationwide.
Purpose-built for a mobile-driven market
With one of the globe's highest 5G adoption rates—45% of the population as of 2022—South Korea exemplifies a mobile-first payment culture. This makes cashless payments in South Korea not just common—but culturally expected. Even before the pandemic, digital payments had already outpaced cash, with just 14.6% of transactions in 2021 made using physical currency. Toss Pay aligns with and accelerates this behavioral shift.
Multi-channel, cross-border utility
Toss Pay supports a wide spectrum of domestic and international use cases. It is accepted on major platforms such as Coupang—South Korea's dominant e-commerce force—and across Alipay+ affiliated networks in 42 countries, including the U.S., Japan, Australia, the U.K., and Singapore. For overseas purchases, funds are debited in Korean won and settled instantly, eliminating the complexity and friction of manual currency exchange.
