The PIN code is the first line of defense of the Card Card. It is he who allows you to raise money or make payments at physical terminals. However, many users continue to opt for simple and easy to guess, which puts the safety of accounts at risk. Choosing a safe pin may seem like a small detail, but it is an essential step in protecting money and personal data.
In addition to functioning as an access key, PIN is also an indicator of financial prudence. Even if online operations require other authentication mechanisms, protection in the physical world continues to depend on this four -digit code.
Predictable codes risks
The site specializing in economics and current, Marketeer warns that choosing obvious numbers, such as “1234” or birthday dates, considerably increases the risk in case of card loss or theft. Easy numbers to guess make access to the account much simpler for criminals, who can try combinations quickly. Although there are thousands of possible combinations, repeated patterns remain very common and therefore attract the attention of those who try to explore safety failures.
Experts recommend creating difficult codes to predict and change them regularly. Avoiding simple sequences or repeated numbers, not using personal dates, are essential measures to reduce vulnerability. A secure pin acts as the first protective barrier before any other bank safety mechanism.
Technology facilitates attacks
The advance of artificial intelligence has made the PIN combinations test much faster. What was once a slow and laborious process can now be performed almost instantly by automated systems. Therefore, predictable codes, which follow obvious patterns, become easy targets for digital attacks, increasing the risk of fraud.
In addition, growing automation of access attempts means that stolen or lost cards can be compromised in minutes. This reality makes it even more important for users to choose random and complex codes, difficult to guess even by sophisticated systems.
Worrying statistics
One study, presented by the same source, analyzed millions of PIN taken from compromised databases and revealed alarming numbers: 11% of the codes were “1234” and more than a quarter could be discovered in up to 20 attempts. Among the most common PINs are also “1111”, “0000”, “1212”, “7777” and “6969”. Birth dates are equally frequent, further reducing safety.
The study shows that, although it seems like a small detail, the choice of PIN is one of the greatest vulnerabilities of the ATM card. With lock systems to limit the number of attempts to three or five errors, even slightly predictable code may be sufficient to open doors to experienced criminals.
Good practices in choosing PIN
To increase safety, it is recommended to choose random sequences that do not follow obvious patterns. A little used code, such as “8068”, is difficult to guess and reduces the risk of automated attacks. Also, you should never share PIN with third parties or write it down in affordable places such as notes or mobile phones.
Avoiding simple repetitions or sequences is just the first step. Regularly change the code and be aware of signs that the card has been compromised helps maintain active protection. Banks never ask for PIN outside the official terminals, so any suspicious request must be ignored and communicated.
Daily protection
When using the card, it is essential to protect the keyboard from the view of third parties to prevent the capture of the code by hidden cameras or indiscreet looks. A simple gesture of covering the keyboard while typing the pin can avoid fraud that materializes in seconds.
In addition, storing PIN in safe places, such as just in memory, and contacting the bank immediately in case of suspicion of commitment, are measures that can spare losses. Daily surveillance and basic care make a big difference in account security.
Multifactorial authentication
Multifatorial authentication is a powerful tool for reinforcing the protection of online accounts. Combine PIN with codes sent to the mobile phone or biometric recognition makes any attempted unauthorized access difficult.
This approach creates additional defense layers, making it much more difficult for criminals to get into the account even if the PIN is compromised. The combination of strong codes and additional verification mechanisms is now considered an essential practice of bank safety.
Take care of your account
It states that, although simple at first glance, PIN is one of the largest vulnerabilities of the card when chosen predictably. With the attack methods to evolve constantly, maintain safe codes, and using additional checks is critical to protecting money and personal data.
Choosing a strong pin and maintaining solid safety habits is not just a recommendation, it is a necessity in the current context, where advanced technology makes the life of cybercriminals easier and easier.
