What it is

Nubank is a Brazilian fintech that works as a digital bank: it offers a checking account, a credit card with no annual fee, and investment options, all managed from your phone. There are no physical branches, which reduces costs and allows lower fees.

What it is

  • Digital account with unlimited free transfers (TED/DOC)
  • International credit card with no annual fee
  • Points program that can be exchanged for products or discounts
  • Personal loans with interest competitive
  • Nubank Invest (CDBs and funds) for those who want to start investing

How it works

Everything happens inside the app: you download it, create a login, upload a photo of your document and, in a few minutes, the account is ready. The credit card arrives in up to 10 days and can already be used for online or in‑store purchases. When you pay the bill, the money comes out of your Nubank account, which works like a traditional checking account but with a simpler interface.

  • Download the app from your phone’s store
  • Register CPF, RG and a selfie for identity verification
  • Choose between opening an account, requesting a card or investing
  • Receive the card and activate it through the app with a tap
  • Use the QR Code or the Pix key to receive and send money

Advantages

Nubank’s proposition is to make banking services more transparent and cheaper. By not having branches, the company can eliminate most of the fees charged by traditional banks. In addition, customer service is provided via 24 h chat, which is usually faster than the phone lines of older banks.

Advantages

  • Zero annual fee on the credit card
  • Free and unlimited transfers and DOCs
  • Withdrawals at Banco24Horas network with no fee (up to 4 per month)
  • Full control from the phone: block, limit and bill in real time
  • Simple rewards program, without complicated rules

Risks

Even with many advantages, using a fully digital bank has some points of attention. First, the dependence on the internet: if the phone freezes or the network drops, you may be left without immediate access to your money. Second, the credit limit can be automatically adjusted by the algorithm, which sometimes surprises people used to fixed limits. Finally, although the Credit Guarantee Fund (FGC) covers up to R$ 250 mil per institution, the total value deposited is still subject to market risks in the investments.

  • Need for a stable connection for transactions
  • Credit limit subject to automatic reviews
  • FGC coverage limited to R$ 250 mil per CPF
  • Investments can lose value in high‑volatility scenarios

Practical examples

Imagine three friends who earn different salaries and decide to use Nubank to organize their financial lives.

  • Ana, who earns R$ 3,200, uses the card to pay grocery shopping and pays the bill in full every month. She takes advantage of the points program and redeems 1,500 points for a R$ 50 gift‑card, saving on the next purchase.
  • Bruno, with a salary of R$ 5,500, opens the digital account and schedules automatic debit for the electricity bill. He also makes a monthly deposit of R$ 1,000 in Nubank Invest, earning about 8 % per year in CDBs, which generates roughly R$ 80 of interest at the end of the first year.
  • Carla, who receives R$ 7,800, requests a personal loan of R$ 5,000 to remodel her house. The contract has a rate of 1.9 % per month, and she pays it in 12 installments of R$ 466, which fits the budget without needing to resort to higher‑interest credit cards.

Practical tip: always pay the Nubank credit‑card bill before the due date to avoid interest and keep your credit score high.

Practical tip: use the “Goal” feature of the app to set aside money for trips or emergencies; the balance is locked and automatically earns interest.

Practical tip: set up alerts for credit‑limit changes and low‑balance notifications; this helps you avoid surprises and better control your spending.
