If the “Disagree” option is selected for three times to the registration declaration for the “Smart Immigration Clearance” that displayed on the screen of the first gate of the “joint inspection automated channels” installed at the Hengqin Port, then the prompt containing the declaration will not appear when the passenger passes through for the fourth time. Afterwards, he is required to visit one of the designated service locations in order to apply to register for the “Smart Immigration Clearance”. When passing through the automated clearance channel, he must tap the “Agree” button appeared on the registration declaration, in order to enable the records taken by the frontier inspection authorities of Macao and Mainland.
