What is the use of dynamic password card of China Bank? I can use SMS verification code when transferring money in mobile banking, so the role of dynamic password is useless.

1. Order E of China Bank is our brand name, which is used to use dynamic password card as a security authentication tool. Dynamic password board is a kind of special hardware with built-in power supply, password generation chip and display screen, which can automatically update dynamic passwords regularly according to special algorithms. The system based on this dynamic password technology is also called OTP system, that is, the user's authentication password is changed, and the password will be invalid after being used once, and the password for the next login is a completely different new password. As an important two-factor authentication tool, dynamic password card is widely used in the field of security authentication. Dynamic password card can greatly improve the security of online banking/mobile banking. Our dynamic password is updated randomly every 60 seconds, and the password is displayed as 6 digits. 2. The transaction range supported by "mobile phone transaction code" is the same as "dynamic password+mobile phone transaction code", but the transaction limit is different. This authentication method is suitable for small transactions. For details about the limit, please refer to the portals "Bocnet" and "BOCNET" and "Bank of China".
