On September 3, 2026, the Central Bank of Brazil (BCB) released version 7.4 of the Manual of Minimum Requirements for Pix User Experience, focusing on improving the transaction dispute resolution journey through the Special Return Mechanism (Mecanismo Especial de Devolução, MED) and reinforcing security and information clarity for users. The new requirements enter into force on March 1, 2027, providing participating institutions with adequate time to adapt their applications. The updated manual introduces a more informative dispute journey for the MED, which has been available since October 1, 2025. Based on nearly one year of operational experience, the BCB identified opportunities to enhance recommendations to better serve fraud victims and provide institutions with higher-quality information. The new journey facilitates identification of fraud types through everyday language scenarios and enables users to contextualise and detail incidents, including attaching supporting documents. The updated journey also better directs users when reported situations are ineligible for MED coverage, such as commercial disagreements not involving fraud, preventing unwarranted expectations and directing citizens to appropriate support channels. The core MED rules remain unchanged, including the 80-day maximum period to request returns and the 11-day deadline for institutions to inform users of dispute outcomes. Additional amendments prohibit including advertisements, promotional content, commercial offers, hyperlinks or transaction-unrelated materials in Pix payment receipts, reducing fraud vector risks. The manual also establishes requirements for favorite contact functionality, requiring storage of the Pix key used in transactions and mandatory alerts when recipient identification changes. For Automatic Pix, the payment purpose field now appears prominently alongside recipient identification. The BCB reinforces standardised, clearer messaging across various user journeys, including key initiation, QR code usage and key management, particularly in situations involving suspected fraud. These changes reflect the BCB's ongoing security and evolution agenda for Pix, balancing user protection with the simple, efficient experience characterising the system. Version 7.4 is available on the BCB's website, and Normative Instruction BCB No. 774 provides the full regulatory text.
