Nubank leverages AI to scale Pix operations

São Paulo, December 10, 2024 - Nubank is expanding Pix using generative artificial intelligence, both on its app and via WhatsApp. Now, more customers can transfer money by giving commands using audio, text, and image messages, ensuring convenience, safety, and speed, alongside a smoother experience and safety.

Pix with AI in the Nubank app uses technology to speed up processing, reducing transaction time by up to 60%, without compromising the security ensured by the app's defense mechanisms. To access this feature, customers should go to the Pix Area, click on the purple bar at the top of the screen, and follow simple instructions.

On WhatsApp, the feature was tested by 2 million customers since October. The key difference is that transactions can be done directly on WhatsApp, eliminating the need to open the Nubank app, which is only used in the activation step. The payment process is fully integrated and simple. During the testing phase, transactions are limited to R$200, with a daily maximum of R$2,000 or according to the user's Pix limit, with the lower amount prevailing. To use this feature, the customer must click "Pix on WhatsApp" in the Pix Area of the Nubank app and is automatically directed to WhatsApp to interact with the AI. Another way to access it is by sending a message to (11) 5039 3944. The profile displayed will be Nubank's, with WhatsApp's verification badge, ensuring authenticity.

In both versions, it's possible to send a Pix using audio, a short message, or an image with the recipient's name and amount. Transfers are instantaneous and fee-free. As is common with technologies involving generative artificial intelligence, there is a learning curve as more customers use it. The functionalities are also expected to receive future improvements from the use cases currently in testing, such as Pix on Credit support, allowing installment payments using Pix.

As is the case with all product development at Nu, the solution underwent a testing phase with a small customer base to make the necessary adjustments before scaling to other users. Now, with the addition of millions of customers, the product maturity process will be even more accelerated, continuing the platform's evolution process.

Secure Transactions

Both solutions have fraud prevention technology. At Nubank, customers benefit from Smart Defenses, a set of solutions that customers can't see but work continuously to protect them. This way, Nubank can anticipate possible attacks that arise from pattern breaches. Moreover, all risk analyses conducted on the app are also available on WhatsApp. For this version, the daily and per-transaction Pix limit will apply.
