Step By Step Guide Shows How To Use The New Pix Refund System Through The Special Refund Mechanism, Activate The Dispute Button In The App After A Scam, And Understand Blocking, Analysis, And Refund Timelines To The User, Mandatory For Banks Starting In February 2026 In Brazil.
The new model of the Special Refund Mechanism, the MED, which was created to facilitate the refund of Pix in cases of fraud or operational errors by financial institutions, is now in effect. The major change is that the system allows tracking and blocking amounts even after several transfers, which makes life difficult for scammers and increases the chances of recovering the money. For the user, this means learning in practice how to use the new Pix refund system directly in the bank’s app.
Currently, the use of the MED is still optional for institutions, but the rule is already set. Starting on February 2, 2026, all banks and participating institutions must use the new Pix refund mechanism. Until then, it is essential for the customer to get used to the dispute button in the app, understand the response timelines, and know in which situations the tool works or does not work.
How The New Special Refund Mechanism Works
The MED is the system that makes the refund of Pix possible when the customer is a victim of fraud or when there is proven operational error by the financial institution.

A new Brazilian shopping center worth R$ 400 million will be built in an area equivalent to more than 4 football fields, featuring 90 stores, 5 cinemas, a supermarket, a college, and parking for 1,700 cars, potentially generating 3,000 jobs.

Larger than entire cities in Brazil: BYD is building a 4.6 km² complex in Bahia with a capacity for 600,000 vehicles per year, but the discovery of 163 workers in conditions analogous to slavery has shaken the entire project.
-
With an investment of R$ 612 million, a capacity to process 1.2 million liters of milk per day, Piracanjuba inaugurates a mega cheese factory that increases national production, reduces dependence on imports, and repositions Brazil on the global dairy map.

Brazilian city gains industrial hub for 85 companies that is equivalent to 55 football fields.
Previously, blocking and refund could only be done from the account that directly received the Pix. Now, with the new model, it is possible to track the money trail and block amounts in other accounts to which the scammer attempted to send the resources.
In practice, this means that if the money is quickly transferred to various accounts, the MED can follow the trail of transfers within the financial system.
The data from these transactions is shared among the institutions involved, which increases the chance of locating and securing the amount.
The Central Bank’s goal is to prevent the scammer from hiding or dispersing the money before the bank can take action.
Dispute Button In The Bank’s App
Since October, the apps of financial institutions have included a dispute button integrated with the Special Refund Mechanism. This option usually appears with names like “Dispute Pix,” “Report Fraud,” or “Request Refund,” almost always in the statement area or on the transaction screen itself.
The main advantage is that by activating the Pix dispute button directly in the app, the customer does not need to call the customer service center or seek other channels.
The request immediately enters the MED flow, which makes blocking the amounts faster and increases the chance of recovery.
The sooner you activate the button, the greater the possibility that the system will locate the money before it is withdrawn or transferred.
Step By Step Guide To Use The New Pix Refund System In Case Of A Scam
To understand in practice how to use the new Pix refund system, it is worth following the basic step by step in case of suspicion or confirmation of fraud.
- Access Your Bank’s App
Open the app of the institution where you made the transaction via Pix. Do not wait until the next day; do this as soon as you notice the scam or suspicious behavior. - Find The Pix Dispute Button
Look for options like “Dispute Pix,” “Request Refund,” or “Report Fraud.” This function is already integrated with the MED and is the official path to initiate the refund of Pix in case of a scam. - Register The Refund Request
Inform the app that you have been a victim of a scam, fraud, or coercion. It is important to describe what happened clearly. The deadline to register the dispute is up to 80 calendar days after the Pix transaction, so do not leave it for later. - The Institution Conducts A Preliminary Analysis
After receiving the request, the bank assesses whether there are indications of fraud or error by the institution. If there are consistent signs, the amounts begin to be blocked in the involved accounts. This initial blocking is essential for the Special Refund Mechanism to retain the money while investigating the case. - Monitor Response and Refund Timelines
If fraud is confirmed, the refund of the money may occur within up to 11 days after the complaint is registered, either totally or partially, depending on the available amount. In some operational flows, the institution works with internal analysis and response stages with shorter timelines within this limit, but the maximum deadline provided is up to 11 days for the refund when the scam is proven.
Blocking, Analysis, And Refund Timelines For The Money
In addition to the deadline of up to 80 days to request the dispute and up to 11 days for the refund after registration, the new MED model provides another important measure.
If the amount is not fully available immediately, the bank may make successive blocks for up to 90 days in the receiver’s account, until reaching the total that needs to be refunded to the victim.
This is useful in cases where the scammer spends part of the money but is still active in the account. As long as there is movement and balance, the system can continue to block amounts until completing the Pix refund, within the 90-day limit.
It is a mechanism designed specifically to deal with criminals who are consuming the amount in smaller parcels.
Cases Where The Pix Refund Does Not Apply
Not every payment problem can be resolved by the MED. The refund of Pix through the Special Refund Mechanism applies exclusively to cases of proven fraud or error by the financial institution. Some situations are excluded from the new system and need to be addressed directly between the parties.
Among the cases not covered by the MED are:
- Commercial disagreement, such as a product that was not delivered or a service provided unsatisfactorily
- Sending Pix to the wrong person due to the user’s own mistake
- Conflicts between individuals of good faith, without fraud involved
In these situations, the Central Bank does not activate the MED. The path goes through direct negotiation, customer service channels of the establishment, or even consumer protection agencies, but not through the new Pix refund system.
How To Protect Yourself And Act Quickly In Case Of A Scam
The MED and the Pix dispute button are important reinforcements, but they do not replace daily care with passwords, apps, and data confirmations.
It is essential to be suspicious of messages that pressure for urgent payment, investment offers with guaranteed returns, and links sent by unknown individuals.
If even with all precautions you fall for a Pix scam, the most important thing is speed. The sooner the user understands how to use the new Pix refund system and activates the request in the app, the greater the chances of recovering the money through the Special Refund Mechanism. After registering the dispute, it is advisable to keep protocols, screenshots, and any evidence that helps in the bank’s analysis.
In the end, the new MED transforms Pix into a safer system for those acting in good faith, but it does not completely eliminate the risk of scams.
The combination of information, agility, and correct use of the Pix dispute button is what makes the difference between losing everything and having at least a partial refund of the amount.
And you, do you already know how to use the new Pix refund system and would you activate the dispute button in the app immediately if you suffered a scam?
