Nubank Explained: Digital Banking Without Branches

Nubank is a Brazilian digital bank that operates entirely without physical branches, offering a no-fee credit card, a digital checking account, and investment products through its mobile app. As of 2026, it is one of the largest fintechs in Latin America, with over 90 million customers across Brazil, Mexico, and Colombia. This guide explains what Nubank is, how it works, its main products, fees, and security measures, helping you decide if it fits your financial needs.

What Is Nubank?

Nubank is a Brazilian digital bank that operates entirely without physical branches, offering a no-fee credit card, a digital checking account, and investment products through its mobile app. Founded in 2013 by David Vélez, Cristina Junqueira, and Edward Wible, Nubank has grown to become one of the largest financial institutions in Latin America. It is a financial technology company, not a traditional bank, but it operates under a banking license issued by the Central Bank of Brazil, ensuring regulatory oversight and deposit insurance.

Why Nubank Matters in 2026

Nubank matters because it represents a shift in how people access banking services, especially in emerging markets. According to the World Bank’s 2021 Global Findex Report, about 70% of adults in Latin America have an account, but many still rely on cash and informal services. Nubank has helped bring millions of unbanked and underbanked individuals into the formal financial system. In 2025, Nubank reported a customer base of over 90 million, with a net income of $1 billion in 2024, according to its shareholder letters. Its success has forced traditional banks to lower fees and improve digital offerings, benefiting consumers across the region.

Who Is Nubank For?

Nubank is designed for anyone who wants a simple, low-cost banking experience, but it is particularly appealing to:

• Digital natives who prefer managing finances via smartphone.
• Fee-conscious consumers who want to avoid monthly maintenance fees and high interest rates.
• Underbanked individuals who lack access to traditional banking services.
• Frequent travelers who need a card with no foreign transaction fees.

However, Nubank may not be ideal for those who require in-person services, cash deposits, or complex business banking features.

How Does Nubank Work?

Nubank operates as a fully digital bank, meaning all interactions occur through its mobile app or website. To open an account, you download the app, provide basic personal information, and undergo a digital identity verification process. Once approved, you receive a virtual card instantly and a physical card within a few days. You can manage your account, pay bills, transfer money, and access support via the app’s chat. Nubank uses a proprietary credit analysis algorithm that considers alternative data, such as payment history and spending patterns, to approve credit cards for customers who might be rejected by traditional banks.
