Approach payments have become a common habit, especially in quick everyday purchases. With the generalization of NFC technology, most of the ATM payment terminals allow you to complete transactions only with one touch of the card or mobile phone.
However, there is a technical detail that many ignore and can make all the difference: at the end of the operation, all legitimate terminals always emit a sound, being a beep, a click or even a brief vibration, as a sign that payment has been successfully processed.
Confirmation Sound: a warning against fraud
In recent years, the Public Security Police (PSP) has registered an increase in burlas associated with “mute” multibanco terminals, which do not issue sound or generate proof, despite debiting values in the customer’s account.
These equipment, often falsified or modified, allows the manual introduction of higher than reais or duplication of payments without the user noticing, according to a site specializing in lifestyle, Leak.
Frauds occur mainly in busy places, such as fairs, festivals and small establishments. The burns take advantage of the flow of people to operate for a few minutes, making multiple victims before they disappear.
The NFC system creates a safe connection between the card or smartphone and the terminal, but may be the target of technical interference or fraudulent intentions.
The absence of confirmation or proof sound is warning signs that should lead the user to confirm the value on the screen before validating payment.
How to avoid being deceived
Among the errors that facilitate these fraud is the acceptance of payments without sound or confirmation light, not checking the amount displayed at the terminal, does not activate immediate notifications in the banking application and leave the NFC mode permanently active on the card or smartphone.
To avoid being a victim, it must always confirm whether the terminal issues sound or vibration, if the amount presented corresponds to the expected and receives immediate notification from the bank. It is also important to verify that the terminal appears to be in good working order.
As alerts A, if you detect any irregularity, you should contact the bank and file a complaint to PSP. Sound confirmation, albeit brief, is a key element to ensure that the transaction has been processed correctly and corresponds to the intended value, adds the same source.
