What is a dynamic password card?

With my bank card and ID card, I will give you a dynamic password card when I open online banking at the counter of China Bank. The advantages of BOC online banking dynamic password card are not only very safe, but also very convenient to use. Users can bring valid identity documents (enterprise customers need to provide organization code and application form) to the designated business outlets of Bank of China to apply for opening the dynamic password card for online banking of Bank of China, and pay relevant fees. With the approval of Bank of China, dynamic password cards can be issued to users.

China Bank's online banking dynamic password, also known as one-time password, is updated randomly every 60 seconds. Its advantage is that one password is only used once in the authentication process, and another password will be used in the next authentication, which makes it difficult for criminals to impersonate legitimate users, and users do not need to remember passwords.
