Caixa, the Brazilian government-owned bank responsible for PIX, has confirmed that the system encountered a brief period of instability earlier today. However, the issue has been resolved, and PIX is now fully operational. Caixa has not provided any specific details regarding the cause of the outage, but it is believed to have been a minor technical glitch. PIX, which was launched in November 2020, has quickly become one of the most popular payment methods in Brazil, with over 100 million registered users. The system allows users to make instant payments and transfers between different banks and financial institutions using only a mobile phone number or QR code. The outage, while brief, may have caused some inconvenience to users, but it is a reminder that even the most reliable systems can experience occasional disruptions. Caixa has assured users that PIX is now operating normally and that they can continue to use the service as usual.
