"A key opens a lock. So, when someone else knows your bank card number, is it like losing your keys, which poses a security risk?
The card number itself is like the "house number" of the account, and this information alone does not provide direct access to the funds in the account. But that doesn't mean it's completely risk-free. If the card number is leaked along with other sensitive information (such as passwords, CVV codes, expiration dates, etc.), the risk is greatly increased. Imagine if someone knew both your card number and the security code behind the card, then it was possible for them to make a transaction without two-factor authentication.
That's why it's important to protect your card information. For example, avoid talking about your card details out loud in public or entering them on insecure** places. If you accidentally leak your bank card number, pay attention to your account activity immediately and replace your card in a timely manner.
In addition, using the security services provided by the bank, such as SMS notifications, transaction alerts, etc., it is possible to stay informed about the unusual activity of the account. In the case of suspected information leakage, contacting the bank in time to freeze or replace the card is an effective means to prevent property loss.
Finally, everyone is reminded to be vigilant when dealing with any banking matters, especially when providing personal and banking information. Remember, when you protect your financial information, you keep your property safe. Security awareness is an important part of financial activities and should not be taken lightly.
