In the testing phase, only a group of PJ Account customers will be able to use Nubank's PJ credit card. If you are a customer and already have a debit card, you will see the option to register your interest in the credit function in the app. If you don't have this option, you'll have to wait a little longer. If you're an Account customer but don't have a debit card yet, you'll need to apply for yours and then see if you can register your interest in the app. If your time hasn't arrived yet, rest assured that we're working hard to unlock more customers as soon as possible!
