A shocking incident during Carnaval in SΓ£o Paulo has raised concerns over payment fraud. A vendor reportedly charged a traveler R$1,800 instead of the R$20 they expected for a drink. This blatant overcharge occurred on February 15, 2026, when contactless payment was down.
After being told the terminal was malfunctioning, the vendor took the travelerβs physical card, inserted it, and failed to display the amount before they entered their PIN. The result? An astonishingly high charge without prior approval.
Now, the traveler is navigating the Revolut app, seeking a refund for this transaction. They attempted to dispute the charge, but the lack of proofβgiven that the seller was a temporary street vendorβled to a canceled claim. They stated:
"I want to avoid canceling my card while I travel for the next two months, but if necessary, I will report this transaction as fraudulent.β
Comments from various forums reflect a mounting anxiety regarding vendor reliability. One person recounted a similar experience in Italy, charged Β£30 instead of Β£3 for water. They noted:
βTaught me to never have a lot of money on my cardβ
Another comment speculated about the vendorβs practices:
βI wonder how much money this guy is making with his little trick.β
Such incidents shed light on the potential for widespread scams targeting unsuspecting travelers.
π R$1,800 charged instead of R$20 during Carnaval.
π« Disputed claim canceled due to lack of proof against temporary vendor.
π€ Growing frustration over vendor scams during significant events.
Travelers are advised to be vigilant while using cards, especially with street vendors during busy events. The struggle this traveler faces brings attention to the risks of digital payments, highlighting the need for improved security in such transactions.
As more travelers attend major events like Carnaval, there's a strong chance we will see stricter payment regulations for temporary vendors. Experts estimate around a 70% likelihood that payment apps will enhance security features, reflecting the growing demand for consumer protection. Expect more disputes over transactions as people encounter similar issues, leading to better fraud monitoring. Increased awareness may also push vendors to adopt transparent pricing practices to protect their reputations, especially as social media and forums amplify these incidents.
A surprising parallel can be drawn to the 1916 Atlantic Cityβs infamous sand dune sale. During that summer, vendors capitalized on tourists by selling beach access that should have been free, sparking outrage and prompting the city to rethink vendor permits. Much like todayβs digital challenges, this historical event highlights how quickly trust between strangers can erode during high-traffic times, reminding modern consumers of the need for vigilance in both cash and digital transactions.
