Nubank is a digital bank based in Brazil with over 100 million customers, and for younger users it's often effectively their 'first financial app.' Even in a market where Pix accounts for over roughly 40% of online payments, Nubank customers can choose balance, card, or installments from within the NuPay button inside the app, and this tends to produce a higher completion rate than card-entry payments.

For subscription services and commerce sold primarily through mobile apps, and for fashion, beauty, and gaming merchants with a high share of customers in their 20s and 30s, NuPay lets you target Nubank's customer base precisely. Since the merchant never handles card information, it can also reduce drop-off among customers concerned about payment security.

When a consumer selects NuPay at checkout, an approval request is sent to the Nubank app, and the consumer approves the payment by choosing account balance or a card (including installments) inside the app. It's an in-app approval structure where no card number is entered into the merchant's checkout screen. Hecto Financial receives the approved funds in BRL, converts them, and settles the merchant in Korea in the contracted currency among USD, KRW, or JPY.

Through Hecto Financial, merchants in Korea can consider adopting NuPay without entering into a separate contract with Nubank. Since it's an in-app approval method, you also need to review the conversion flow within your mobile web and app checkout UX, and availability and terms are determined based on industry and transaction-volume review.

• Business registration country

  Confirm contract eligibility for merchants registered in Korea

• Sales channel

  The integration method and priorities differ depending on your online sales channel mix, such as your own site, open marketplaces, or mobile apps

• Product category

  Confirm in advance whether your category falls under restricted industries per NuPay's operator merchant policy

• Local regulatory compliance

  Confirm compliance with Brazil's payment and foreign exchange regulations (see official sources below)

NuPay revenue is received in BRL and, after conversion, paid out in the USD, KRW, or JPY specified at contract time, with the settlement cycle following the contract terms. Refunds are returned to the consumer's Nubank account based on the original transaction, and it's good practice to reflect a refund-processing deadline in your internal policy that accounts for the 7-day right-of-withdrawal period set by Brazil's CDC.
