Core Viewpoint - The article discusses the functionality of the electronic tax bureau that allows taxpayers to set the duration for facial recognition authentication when issuing blue invoices, aiming to improve work efficiency. Group 1: Facial Recognition Authentication - The electronic tax bureau has a feature called "Facial Recognition Duration Setting" that allows the legal representative or financial responsible person to adjust the facial recognition authentication time interval to enhance invoice issuance efficiency [1][2]. - The system calculates the maximum facial recognition duration based on the taxpayer's situation, tax payment credit, and risk level [2]. Group 2: User Permissions - The "Facial Recognition Duration Setting" feature can only be operated by the legal representative and financial responsible person, while tax handling personnel and invoicing personnel do not have this operational authority [2].
