Credit card security has always been a potential fear among cardholders. After all, the leakage of personal information is a serious matter. So, how should we prevent ourselves when using credit cards?

1. Apply for a credit card through formal banking channels. Do not entrust others or illegal intermediaries to handle the application to avoid leakage of personal information.

2. Keep the card and password properly. The password setting cannot be too simple. Do not disclose important information such as card number, validity period, security code, password to others on a daily basis to prevent the card and password from being stolen at the same time.

3. Be careful when making card transactions. Do not allow the card to leave your sight, and be careful to block the gestures when entering the password. When someone else distracts your attention, you should cover the card opening with your hand to prevent the card from being dropped. After the operation is completed, you should take out the card in time and keep it properly.

4. When the reserved phone number, billing address, mailbox, etc. change, the bank should be notified in time for updates.

5. Be wary of abnormal account activities or bank system upgrades, and be careful of emails, websites, phone calls, etc. that require bank card numbers, passwords, card validity periods, and SMS verification codes.
