How does China Construction Bank change transfer verification code into withdrawal code verification?

When using mobile banking to transfer money, you cannot change the SMS verification code into the password of the bank card. SMS verification code is equivalent to the payment password of electronic bank, which ensures the payment security of electronic bank.

When customers use electronic banking to conduct transactions, in order to ensure that the payment security verification is handled by themselves, it is necessary to send a verification code to the mobile phone number reserved by the customer, and the payment can only be made after the verification code is correctly entered.
