Will there be security problems if the bank card number and mobile phone number are leaked?

If only the bank card number and mobile phone number are leaked, there is no risk. The key is that the bank card password can't be leaked, especially the verification code received on the mobile phone number can't be leaked, and the ID number can't be leaked.

However, if the bank card is bound to the mobile phone, there will be certain risks and the deposit may be stolen.

Extended data:

When these situations indicate that the bank card information has been leaked, the abnormal situations include:

1. Received an abnormal transaction short message from the bank that was not my own behavior;

2. The SMS reminder of bank account change has been activated, but the mobile phone cannot receive any SMS for a period of time;

3. Received a fake bank message, and the personal information and card information are correct;

4. Enter the bank card information on the website where the security cannot be confirmed, or accidentally click the Trojan link in the suspicious short message;

5. Reveal the positive and negative information of the card to strangers;

6. When the merchant swipes the card at POS or uses the bank card at ATM, he finds that the equipment is abnormal;

7. Have used bank cards in places or regions where risks occur, and have received risk warnings from banks.

If you encounter these situations, you don't have to panic too much. If criminals want to steal credit cards, they need to obtain SMS verification code. At this time, if the card has not been stolen, you can change the password as soon as possible. If you still have an old-fashioned magnetic stripe card, you should report the loss as soon as possible and replace it with a chip card.
