Claude Samsung Pay payments — how to top up Claude API and Claude Code with Samsung Pay, with a 2 million won limit

Claude Pro and Max cannot be paid for with Samsung Pay either on the website or in the app. Claude API and Claude Code can be topped up with Samsung Pay on Kunavo's Korean-won checkout page, up to 2 million won per transaction.

How Claude payments with Samsung Pay work depends on what you are paying for. claude.ai Pro·Max를 웹에서 구독하면 Anthropic은 신용카드와 직불카드만 받습니다(Anthropic billing FAQ, October 3, 2026 확인). 앱에서 구독할 때 결제를 처리하는 App Store와 Google Play의 한국 결제 수단 목록에도 삼성페이는 없습니다. 그래서 Claude 구독은 어느 경로로도 삼성페이로 낼 수 없습니다. 삼성페이로 결제할 수 있는 쪽은 Claude API and Claude Code run with an API key입니다. Kunavo 잔액을 충전할 때 결제 화면이 원화(₩)로 뜨면 갤럭시 폰의 삼성 월렛으로 승인할 수 있고, 한 번에 낼 수 있는 금액은 Stripe 기준 200만 원까지입니다. 충전은 $10부터입니다.

검색하다 보면 ‘삼성’이라는 글자에 속기 쉽습니다. Google Play 한국 결제 수단 목록의 ‘삼성’은 카드 발급사인 삼성카드이고 간편결제 삼성페이가 아닙니다(Google Play payment methods, October 3, 2026 확인). 삼성페이에 넣어 둔 카드 번호를 claude.ai나 스토어에 직접 입력할 수는 있지만, 그건 카드 결제입니다. 아래 내용은 October 3, 2026에 다시 확인했고, 바깥 문서에서 가져온 사실에는 출처를 달았습니다. 갤럭시 폰이 손에 있다면 First create a Kunavo account 이어서 읽어도 됩니다.

What Samsung Pay can and cannot be used for

The middle column of the table refers to paying with the Samsung Pay button; the right column refers to entering the number of that same card registered in Samsung Wallet. The answer differs between the two cases even for the same card.

Anthropic은 PayPal이나 Venmo 같은 제3자 결제 서비스를 받지 않는다고 밝힙니다(Anthropic payment-method guidance). 카드를 해외 결제로 쓸 때 막히는 이유와 Console 결제 절차는 Complete guide to Claude payment methods에 따로 정리했습니다.

“Samsung Pay international payments” is a different feature

‘삼성페이 해외결제’를 찾으면 해외여행 이야기가 나오는 데는 이유가 있습니다. 삼성이 안내하는 삼성페이 해외결제는 NFC 표시가 있는 해외 매장에서 휴대폰을 대고 결제하는 기능이고, 해외 유심으로 바꾸기 전에 국내 유심 상태에서 미리 등록해야 합니다. 삼성은 해외에서는 NFC 방식으로만 결제된다고 적어 둡니다(Samsung Wallet guidance, October 3, 2026 확인). 그러니 이 설정을 켜도 해외 AI 서비스의 온라인 결제 화면에 삼성페이 버튼이 생기지는 않습니다.

Kunavo 충전은 해외결제 등록과 상관없는 원화 온라인 결제입니다. 결제 화면에서 삼성페이를 고르면 Stripe가 한국 결제 대행 파트너 화면으로 보내 인증과 승인을 받은 뒤 다시 Kunavo로 돌려보냅니다(Stripe Samsung Pay documentation, October 3, 2026 확인). Stripe는 이 수단을 한국에 있는 고객용으로, 원화(KRW) 결제에만 제공합니다. 삼성도 온라인 결제는 쇼핑몰과 카드사에 따라 다를 수 있다고 안내하므로(Samsung Wallet guidance), 거절되면 다른 카드나 다른 수단으로 결제하세요.

What you need

  • A Galaxy phone that supports Samsung Pay payments. 삼성전자서비스의 지원 모델 목록에는 갤럭시 스마트폰만 있습니다. S·노트·A·J·Z 폴드·플립 시리즈와 국내 모델인 버디·점프·퀀텀·와이드 시리즈 등입니다(Samsung Electronics Service, October 3, 2026 확인). 아이폰과 다른 제조사 폰은 목록에 없고, 갤럭시 탭도 목록에 없습니다.
  • A credit or debit card registered in Samsung Wallet. 삼성은 일부 카드는 삼성페이에 등록되지 않을 수 있다고 안내합니다(Samsung Wallet guidance).
  • Biometric authentication or a payment PIN. You use it at the final payment step.
  • A Kunavo account and $10. This is the smallest top-up tier, and even after conversion to Korean won it remains comfortably between Samsung Pay's minimum amount (100 won) and maximum amount (2 million won). The balance is prepaid, decreases only by the amount used, remains available indefinitely, and is not deducted for failed requests. For reference, Claude Haiku 4.5 costs $0.70 per 1M input tokens.

Samsung Pay-specific limit: 2 million won per transaction, one-time payments only

  • From 100 won to 2 million won per transaction. Stripe 결제 화면에서 삼성페이로 받을 수 있는 금액의 범위입니다(Stripe Samsung Pay documentation, October 3, 2026 확인). Kunavo 충전 단계 중 $10·$100·$1,000는 환전 수수료를 더한 원화 금액으로도 이 범위 안에 들어갑니다. $5,000는 원화로 200만 원을 훨씬 넘어 삼성페이로는 낼 수 없으니, 카드·국내 카드·Link로 결제해야 합니다.
  • It cannot be saved and charged again. Stripe는 삼성페이를 결제 모드에서만 지원하고 설정 모드와 구독 모드는 지원하지 않습니다(Stripe Samsung Pay documentation). Stripe의 한국 결제 수단 표에서도 삼성페이는 PAYCO와 함께 일회성 결제만 지원합니다(Stripe Korean payment guidance). 그래서 삼성페이 충전은 매번 직접 합니다.
  • Automatic top-ups support cards or Link only. Samsung Pay cannot be saved, so it cannot be connected to Kunavo automatic top-ups (the feature that replenishes the balance when it falls below a specified amount); this feature can be enabled only with a saved card or Link. The same Stripe table also supports recurring payments for Kakao Pay, Naver Pay, and domestic cards, but Kunavo automatic top-ups do not use those methods either.

Top up the Claude API with Samsung Pay on Kunavo

1. Create an account

Create an account with a Google account or email address on the sign-up page. You choose the payment method when topping up, so there is no need to open Samsung Wallet at this stage.

2. Choose a tier within 2 million won

The top-up amounts on the Billing screen are shown in dollars, and the amount in Korean won is determined on the next screen. This is the amount compared with the Samsung Pay limit. Among the current tiers, the amount payable with Samsung Pay is $10·$100·$1,000, and with the bonus added, it is $100 balance after topping up $110, $1,000 balance after topping up $1,200. Large tiers may be locked for new accounts until the first payment is confirmed, so starting with $10 is faster.

3. Distinguish “Samsung Pay” from “Domestic card → Samsung Card” when choosing

Stripe 결제 화면은 접속한 위치에 맞춰 현지 통화로 금액을 보여 줍니다(Stripe documentation, October 3, 2026 확인). 한국에서 열어 금액이 ₩로 나오면 결제 수단 목록에 Samsung Pay가 따로 있습니다. 바로 옆 ‘국내 카드’를 누르면 카드사 목록에 삼성카드가 나오는데(Stripe Korean payment guidance), 이것은 카드사 앱으로 인증하는 카드 결제이고 삼성 월렛을 거치지 않습니다. 삼성페이로 내려면 삼성페이 버튼을 고르세요.

4. Approve in Samsung Wallet

삼성페이를 누르면 앞에서 말한 Stripe 파트너 화면으로 넘어갑니다. 삼성의 온라인 결제 안내를 기준으로 하면, 휴대폰에서 열었을 때는 금액을 확인하고 지문·얼굴 같은 생체 인증이나 결제 비밀번호로 끝납니다. PC에서 열었을 때는 삼성 월렛에 가입한 생년월일과 휴대폰 번호를 넣고, 휴대폰에 온 푸시 알림을 눌러 승인합니다(Samsung Wallet payment guidance, October 3, 2026 확인). 다만 이건 삼성의 일반 안내이고, Stripe 파트너 화면이 PC에서 정확히 이 순서인지는 확인하지 못했습니다. 승인이 끝나면 Kunavo로 돌아옵니다.

5. Use the topped-up balance with an API key

On the Billing screen you returned to, check whether the balance has increased. If the number updates slowly, refresh to confirm it; do not click the payment button again. Then create a key beginning with sk-kn- under Key management (API Keys). The method for checking your first call with curl is covered in Complete guide to Claude payment methods, so it is not repeated here. To run Claude Code using your Samsung Pay balance, enter the Kunavo URL and key as shown below and pin the model.

# 클로드 코드를 구독 로그인 대신 Kunavo 키로 실행합니다.
# 두 변수를 지우고(unset) 새 터미널을 열면 원래 로그인 방식으로 돌아갑니다.

# Opus 5.5는 클로드 코드 v2.1.280 이상이 필요합니다(이전 버전이면 claude update로 업데이트).

The step-by-step setup is described in Claude Code installation and the ANTHROPIC_BASE_URL documentation. With this configuration, Claude Code usage is deducted from your topped-up balance rather than your Pro subscription. Based on Claude Sonnet 5, the input price is $1.40 per 1M tokens and the output price is $7.00; see Claude API pricing for other models.

How currency-conversion fees affect the 2 million won limit

원화 금액은 Stripe가 달러 가격을 바꿔 계산한 값이고, 여기에는 2~4%의 환전 수수료가 들어 있으며 결제하는 사람이 부담합니다. 환율은 24시간 동안 그대로 유지됩니다(Stripe Adaptive Pricing documentation·Stripe support FAQ, October 3, 2026 확인). 삼성페이 한도는 수수료까지 더한 원화 금액에 걸리지만, $10·$100·$1,000 단계는 그래도 200만 원 안에 들어갑니다. 수수료를 피하려고 결제 화면 통화를 달러로 바꾸면 Stripe가 삼성페이를 원화 결제에만 제공하기 때문에 삼성페이 버튼이 사라집니다(Stripe Samsung Pay documentation). 달러 결제와 원화 결제의 비용 비교는 Complete guide에 있습니다.

When Samsung Pay is missing or payment fails

  • The Samsung Pay button itself is missing from the list. If the amount is shown in $, the checkout is not in Korean won. Turn off any overseas VPN, close the checkout page, and reopen it from the Billing screen. If you manually changed the currency to $, switch it back to ₩ and the button will reappear.
  • The amount exceeds 2 million won. This exceeds Samsung Pay's Stripe limit. Choose from $10·$100·$1,000, or pay for a larger tier by card, domestic card, or Link.
  • The card cannot be registered in Samsung Wallet. Use another method on the same Korean-won checkout page. For domestic card, choose the card issuer and authenticate in the issuer's app; Naver Pay, PAYCO, and Kakao Pay are also available on the same page.
  • It is an iPhone or a phone from another manufacturer. Samsung Pay works only on Galaxy smartphones included in the supported-model list. Choose Apple Pay, Kakao Pay, Naver Pay, PAYCO, or a domestic card.
  • The push notification does not arrive on the PC, or the process is stuck on the approval screen. Check that the date of birth and phone number match those registered with Samsung Wallet, and that the phone is powered on. Before paying again, check the Billing screen to see whether the balance has already increased. If you make several attempts in a short period, Kunavo will not accept new top-ups for several hours for security reasons, so one retry is sufficient.

Refunds and documentation

  • The remaining balance is returned to the original payment method. When you close your account, unused balance is returned to the payment method used for the initial payment after payment-processing fees are deducted; therefore, an amount topped up with Samsung Pay is returned as a Samsung Pay payment. Amounts already used for API calls are not refunded (Kunavo Terms of Service).
  • Stripe's 365-day deadline. Stripe는 삼성페이를 포함한 한국 결제 수단의 환불을 원래 결제일로부터 365일 안에만 받고, 고객이 이의를 제기할 수 있는 기간도 결제일로부터 365일입니다. Stripe는 한국 결제 수단이 강력한 인증을 요구해 부정 사용이나 본인이 모르는 결제의 위험을 줄인다고 설명합니다(Stripe Korean payment guidance, October 3, 2026 확인).
  • Check this before processing company expenses: Kunavo does not issue tax invoices, cash receipts, or invoices. Kunavo's record is the top-up history on the Billing screen. Balance and refund rules are summarized in the Billing documentation.

What you can and cannot choose instead of Samsung Pay

삼성페이를 못 쓰는 상황(아이폰, 등록 안 되는 카드, 200만 원 초과)이라도 같은 원화 결제 화면에 다른 길이 있습니다. 카드사 앱 인증이 익숙하면 Domestic card payment, 아이폰이면 Naver Pay나 PAYCO 글을 보세요. 카카오페이와 해외 카드까지 모든 경로를 한 표로 비교한 글은 Complete guide to Claude payment methods입니다. 반대로 토스페이, PayPal, 계좌이체, 휴대폰 결제는 Kunavo 충전에 쓸 수 없습니다. 토스페이는 Apple의 한국 결제 수단 목록에 있어 iPhone 앱 구독에는 쓸 수 있습니다(Apple payment methods list, August 6, 2026 게시).

Frequently asked questions

Can I pay for Claude Pro with Samsung Pay?

No, you cannot. Anthropic states that subscriptions purchased on the claude.ai website can only be paid for with a credit or debit card (Anthropic billing FAQ, checked October 3, 2026). If you subscribe through the app, the App Store or Google Play handles payment, but Samsung Pay is not listed among Apple's payment methods for South Korea (published August 6, 2026) or Google Play's payment methods for South Korea (checked October 3, 2026). You can register a card you have added to Samsung Pay directly as a payment card on claude.ai or in the store. For a claude.ai web subscription, the card must support international payments.

If I subscribe in the Claude app (Google Play) on a Galaxy phone, can I pay with Samsung Pay?

Google Play's payment methods for South Korea are cards, mobile carrier billing, PAYCO, Kakao Pay, Toss, Naver Pay, KCP bank accounts, and Google Play balance (Google Play Help, checked October 3, 2026). “Samsung” appears only as a card issuer (Samsung Card), and Samsung Pay is not listed. Even on a Galaxy phone, you cannot pay for an app subscription with Samsung Pay.

How can I top up the Claude API with Samsung Pay?

Because Samsung Pay is unavailable in the Anthropic Console, top up your Kunavo balance with Samsung Pay. On the Billing screen, choose one of the $10·$100·$1,000 tiers, then on the Stripe checkout page shown in Korean won (₩), select “Samsung Pay” rather than “Domestic card” and approve the payment in Samsung Wallet. This balance is used for Claude API calls and for Claude Code run with your Kunavo key.

Is there a Samsung Pay payment limit?

Yes, there are limits. According to Stripe, Samsung Pay supports payments from KRW 100 to KRW 2,000,000 per transaction (Stripe Samsung Pay documentation, checked October 3, 2026). Among Kunavo's top-up tiers, $10·$100·$1,000 fall within this range, while $5,000 exceed KRW 2,000,000 and cannot be paid for with Samsung Pay. Samsung Pay only supports one-time payments, so it cannot be used for automatic top-ups either. Kunavo automatic top-ups can only be enabled with a saved card or Link.

Can I pay with Samsung Pay on an iPhone?

No. Samsung Electronics Service's list of models that support Samsung Pay payments includes only Galaxy smartphones (the S, Note, A, J, Z Fold, and Flip series, as well as Buddy, Jump, Quantum, Wide, and others), with no iPhones or phones from other manufacturers (checked October 3, 2026). On an iPhone, you can select Apple Pay, Kakao Pay, Naver Pay, PAYCO, or a South Korean card on the same KRW payment screen.

Do I need to configure Samsung Pay for international payments?

The Samsung Pay international payment feature described by Samsung lets you pay by holding your phone near a terminal at an overseas store displaying the NFC symbol. You must register it using a South Korean SIM before switching to an overseas SIM (Samsung Wallet guidance, checked October 3, 2026). Kunavo top-ups are online payments rather than in-store payments. They are processed in KRW on Stripe's checkout page, and Stripe's South Korean payment processing partner handles authentication and authorization (Stripe Samsung Pay documentation, checked October 3, 2026). Samsung states that online payment availability may vary by merchant and card issuer (Samsung Wallet guidance), so if your payment is declined, try another card or pay with a South Korean card, Kakao Pay, or Naver Pay.

Samsung Pay is not showing on the checkout page.

There are usually two possible reasons: the amount is displayed in $ (Stripe only offers Samsung Pay for payments in KRW; Stripe Samsung Pay documentation, checked October 3, 2026), or the selected tier exceeds KRW 2,000,000. In the first case, turn off your VPN and reopen the payment screen, or switch the currency to ₩. In the second case, choose from $10·$100·$1,000. If neither applies and Samsung Pay is still missing, use a South Korean card or another digital payment method on the same screen.

Can the amount topped up with Samsung Pay be refunded?

Amounts already deducted from your balance for API usage are nonrefundable. If you close your account, the remaining balance will be returned to your original payment method after deducting payment processor fees (Kunavo Terms of Service). Stripe only accepts refunds for South Korean payment methods, including Samsung Pay, within 365 days of the original payment date (Stripe guidance on South Korean payments, checked October 3, 2026).
