How does the password used for company checks work? It doesn't transmit signals like a mobile phone, but how do banks know whether the password is correct or not? Thank you.
Enter a fixed element with a password to generate the corresponding password. After receiving the check, the bank will fill in the relevant information under the check before submitting it to the People's Bank of China. When processing a check, the People's Bank of China can judge whether the payment password is consistent with the check by reading the element information from the relevant equipment.
