Infraction Notification (MED)

An Infraction Notification is a formal mechanism used to report suspected misuse or fraud of the instant payment system, in accordance with the guidelines of the Central Bank of Brazil (BCB). This notice is an integral part of the Special Refund Mechanism (MED), provided for in the Pix rules.

The objective is to allow the receiving or paying institution to flag a suspicious transaction and initiate a process to block and/or refund the amounts, in a quick and standardized manner, based on the suspicion of fraud or operational error. It can be used to:

  • Request a refund
  • Cancel a refund
