Can passbook mobile phones be great?

The passbook can be bound with the mobile phone number, because the mobile phone number is bound with my bank account, and the passbook and bank card correspond to my bank account. Passbooks can also be bound to mobile phones through WeChat. The specific operation is as follows: log in to WeChat, click the menu in the upper right corner of WeChat, select "My Bank Card", then add a bank card, and then verify the cardholder, passbook account number and mobile phone number reserved by the bank. After verification, the binding can be successful.
