Anti-fraud technologies can prevent losses of up to R$ 1.5 billion on dates such as Consumer Day, according to Serasa Experian projection

With commercial dates such as Consumer Day, the movement in online and physical commerce grows, making the period one of the preferred targets of scammers. In March 2025, Brazil can register 36 thousand fraud attempts per day that, if effected, are able to generate losses in excess of R$ 220 million. The total for the week of the promotional date would be 250 thousand unsuccessful occurrences and R$ 1.5 billion in financial losses. 

The data is a projection based on the Serasa Experian Fraud Attempts Indicator, the first and largest datatech in Brazil, which records occurrences avoided by authentication and prevention technologies.The director of Authentication and Fraud Prevention at Serasa Experian, Caio Rocha, highlights that promotional dates attract not only consumers, but also criminals, who take advantage of the increase in purchases to apply scams such as card cloning, data theft and counterfeiting of ads and virtual stores. 

“Many consumers are attracted by fake offers, for example, and fall for the impulse blow. To avoid losses, it is essential to distrust excessive discounts, check the credibility of websites and adopt safe practices in transactions. With increasingly sophisticated scams, information and prevention are indispensable to ensure safe purchases and take advantage of promotions without risks”, caio Rocha warns.

To avoid losses on Consumer Day, both in online and in-person purchases, check out the essential recommendations of Serasa Experian:
