Abstract
The invention relates to a one time password inquiry method, including steps of triggering a one time password token, determining whether the trigger is a generation or an inquiry operation, if it is an inquiry operation, inquiring and displaying the latest generated password; otherwise, generating a one time password. Meanwhile, the invention also provides a one time password token with inquiry function, including a trigger module, a determining module, a one time password generating module, a storage module, a display module and an inquiry module. By adding inquiry function, the token meets the need for a user to inquiry a one time password, eliminates the asynchronous problem between the token and a server, and lowers power loss taken by the token.
