Online checkout in Korea is already one tap away. The last friction point is the store counter. A service benchmarking column on Mobiinside compared how Toss and KakaoPay approach in-store mobile payments, and the contrast offers lessons for marketers and retailers alike.
The two flagship products
- Toss FacePay: Register your face and payment method once, then look at the store terminal to pay. It launched fully in September 2025 and passed 6 million cumulative sign-ups by May 2026.
- KakaoPay in-store payments: Barcode, QR and Samsung Pay sit on one payment screen. Partnerships with Samsung Pay and Zero Pay let users pay even at non-KakaoPay merchants. Monthly offline users number about 6 million, with over 500 million payments a year.
Same problems, different answers
1. Paying still means pulling something out
Toss removed the need to pull anything out; the app is used only at registration. KakaoPay reduced choices: one screen handles the payment method and loyalty points. Toss cut steps; KakaoPay cut decisions.
2. Too few accepting stores kills adoption
Toss installed its own terminals through its subsidiary Toss Place, reaching more than 370,000 FacePay merchants by early June 2026. KakaoPay chose alliances with POS and VAN companies, reaching 650,000 merchants and 3 million payment points. That scale came fast, but the checkout experience runs on someone else's hardware.
3. Users need a reason to switch
Toss sells the experience: 60% of first-time users reportedly keep using FacePay. KakaoPay sells the benefits: points, "Good Deal" discounts and membership rewards in one place. In short, "faster" versus "better value."
Why they diverged
KakaoPay already had distribution: it is accepted at over 95% of Korea's top 100 brand merchants, so building terminals would have meant competing with long-time POS and VAN partners. Toss was strong in-app but had no presence at the counter, so it built one, and that gave it a face-payment experience no borrowed terminal could offer.
The marketing takeaway: merchants are the real customers
Neither company charges consumers fees. The business is on the merchant side. Toss terminals automate coupons and return-visit reminders; KakaoPay offers payment-data-based targeted marketing and a "store owner success kit" for local promotion. Owning the payment moment tells you who the customer is and when they come back.
For retailers choosing payment partners, the comparison should include the customer data and retention tools that come with each option, not just transaction fees. KakaoPay is already talking about agentic payments, where an AI handles the purchase inside a chat.
