Have you ever wondered if the secret code of your bank card is secure enough? At a time when fraud is on the rise, choosing a reliable code is more important than ever. Discover how to avoid common mistakes and protect your bank account from potential threats.
The 3 must-know facts
- Overly simple codes, like 0000 or 1234, are easy targets for fraudsters.
- Fraud methods, such as the “collet marseillais,” are commonly used to steal banking information.
- Contactless payments represent a safer alternative, reducing the risk of code theft.
The risks of bank card fraud
Bank card fraud is becoming more frequent, causing significant financial losses to victims. Among the techniques used by thieves, the “collet marseillais” is particularly widespread. This method involves blocking the card in the ATM and discreetly observing the code entered by the user. To protect against these methods, it is essential to choose a complex and hard-to-guess secret code.
Combinations to absolutely avoid
Some secret codes are so common that they become dangerous. Logical sequences or repetitions, like 0000 or 1234, are typical examples of codes to avoid. These combinations are often similar to the most used passwords on the Internet, making them vulnerable to attacks. Expert Nick Berry identified these codes as among the most at risk. It is therefore strongly recommended to avoid them when customizing your bank card code.
How to choose a secure bank card code
To ensure the security of your account, opt for a random code with no apparent meaning. Banks now offer the possibility to change your code via mobile apps, making the process easier. In France, the code is limited to four digits, unlike in Switzerland where it can have six, thus offering increased security.
Contactless payment: a safe alternative
With the rise of contactless payments, whether by card or via smartphone, the risks of fraud by code theft are significantly reduced. This payment method limits the need to enter the code, making transactions safer. This rapidly developing trend could become an essential security standard.
Context: Nick Berry and bank code security
Nick Berry, a former data scientist at Meta (Facebook group), dedicated part of his career to analyzing the risks associated with bank card secret codes. His research highlighted the shortcomings of certain common combinations and emphasized the importance of adopting appropriate security measures. Thanks to his work, many people have become aware of the importance of choosing a complex and secure code for their bank card.
