What it is
KCP, now NHN KCP, is one of South Korea's longest-established payment gateways. It processes credit and debit cards, bank transfers, virtual accounts, mobile billing, and easy-pay wallets for online and offline merchants. For a cross-border merchant, KCP is less a consumer wallet and more the rails that let you accept Korean payment methods in one place.

Where it is mainly used
KCP operates in South Korea and is a major gateway for Korean internet shopping malls and online merchants. It also supports foreign-currency PG services and partnerships for cross-border. If you sell into Korea, KCP is a common behind-the-scenes gateway your PSP may already use.

How customers pay at checkout
At a KCP-powered checkout, Korean customers see local options: domestic cards, bank transfer, virtual account, mobile billing, and easy-pay wallets. KCP handles the two-step authentication and authorisation required by Korean regulation, then returns the result to your store.

How merchants get access
Merchants contract with KCP directly or through a PSP that uses KCP as its Korean gateway. Direct KCP onboarding expects Korean business documents and KYC. KCP also offers developer documentation for integration. Many Korean e-commerce platforms bundle KCP as a selectable PG.

PSP and aggregator route
For cross-border merchants, the simplest route is a global PSP or Korean aggregator that uses KCP under the hood, so you get Korean coverage without a separate KCP contract. Aggregators can also route between KCP, Toss Payments, and Inicis without code changes.
- Use a PSP or aggregator that runs KCP
- No separate KCP contract needed
- Can route between KCP, Toss, Inicis
Pricing and settlement
KCP fees are set in your gateway contract and vary by payment method, volume, and industry. As a gateway, KCP charges processing fees on top of any card association costs. Published pricing is for initial screening only; confirm the provider's official pricing page or a written quote before you go live.

Questions merchants ask
Is KCP a wallet or a gateway?
KCP is a payment gateway, not a consumer wallet. It processes Korean cards, transfers, and wallets (including PAYCO) behind your checkout.
Do I need a Korean company to use KCP?
Direct KCP onboarding expects Korean business documents. Cross-border sellers usually go through a PSP or aggregator that uses KCP.
Can KCP process foreign cards?
Yes. KCP supports major international cards (Visa, Mastercard, JCB) as well as Korean local methods.
What are the fees?
KCP fees are set in your gateway contract and vary by method and volume. Published pricing is for initial screening only; confirm the provider's official pricing page or a written quote before you go live.
Do I need to integrate KCP separately from other gateways?
If you use an aggregator, KCP is one selectable route you can switch without code changes. Direct use needs the KCP integration.
Where do I start?
