Starting in October, customers will be able to contest transactions directly through the Pix environment of banking apps, without needing to contact customer service centers.
According to the BC, this measure will bring more agility and increase the chances that there are still funds available in the fraudster’s account, making the return more viable.
Tracking Accounts
Another important novelty has been established in the resolution. Until now, returns could only occur from the account used in the fraud.
Starting November 23rd, optionally, it will also be possible to recover funds from other accounts involved in the transactions.
This improvement is considered essential because fraudsters often quickly empty the initial account and transfer the funds to others.
Therefore, tracking the paths of the money increases the chances of recovery. The measure will become mandatory starting February next year.
Deadlines and Data Sharing
With the update, returns can occur within up to 11 days after the contestation. The system will identify the path of the funds and share information among the participating financeiras.
The Central Bank emphasized that this data exchange should help block accounts used for fraud, preventing them from being reused in new illegal practices. Additionally, sharing is expected to deter criminals.
Use of the MED
The Special Return Mechanism has been in place since 2021. It can be activated in cases of proven fraud or operational errors by financial institutions.
However, the MED does not cover commercial disputes, situations involving third parties in good faith, or transfers made to incorrect accounts due to the payer’s error, such as incorrect entry of a Pix key.
With the announced changes, the Central Bank hopes to increase the efficiency of the system, protect users, and reduce opportunities for criminals to exploit the country’s most used instant payment tool.
