The emergence of passive electronic lock systems has solved such problems.
The passive electronic lock system can assign unlock permissions to the keys according to the unlock management needs, thereby controlling the access of personnel. The permissions include the list of locks that the key can unlock, the user holding it, the unlocking date and time period. Users who have not been granted the unlocking authority cannot enter the sensitive area. When the relevant staff unlocks and enters, you can clearly see the unlock record in the management software, including the unlocking personnel, unlocking time, lock status, etc. At the same time, it is also convenient for managers to assess management and accountability for accidents.
