It is very dangerous for the bank card number to be known to others. Because your card number is part of your personal information, if it is used by criminals, they may use various means to steal your property or carry out other illegal activities.
First of all, if someone else knows your card number, they may use this information to impersonate your identity and obtain sensitive information such as your account information or password. This way, they can gain access to your bank account and transfer your funds or commit other illegal acts.
Second, if someone knows your card number, they may use various methods to commit fraud. For example, they may contact you by **, text message or email, claiming to be a bank official or relevant department, asking you to provide personal information or make a transfer, etc. If you are not vigilant, you may be scammed into obtaining sensitive information or funds.
In addition, if someone knows your card number, they may use this information to carry out malicious attacks. For example, they may publish your card number on the internet to attract hackers to attack your account or use malware such as viruses to break in. This not only violates your personal privacy, but also poses a threat to your computer system and network security.
Therefore, in order to protect your personal privacy and property security, it is recommended that you do not easily disclose sensitive information such as your bank card number. If you need to provide personal information to the bank or relevant authorities, be sure to confirm the identity and authorization of the other party to avoid being deceived into obtaining sensitive information or funds. At the same time, it is also necessary to strengthen their awareness of network security, update passwords in a timely manner, install anti-virus software and other measures to protect their computer systems and network security.
