PIX Special Return Mechanism (MED)

The Central Bank developed an integration system between banks with the objective of reducing the occurrences and severity of frauds committed involving monetary transactions within the scope of PIX. The system consists of two entities: the infraction report and the return request, and for QI Tech's internal clients, for security reasons, their management is performed internally, avoiding possible frauds.

The flow normally followed is, when identifying a fraudulent transaction, the originating participant must open an infraction report, which the destination participant must investigate and, within a period of 7 days, respond accepting or not accepting it. If it is accepted, the originating participant can again open a return request related to the infraction, which must be accepted by the receiving participant.
