Large airports have applied black technology in boarding, check-in and interchange with other means of transportation, which greatly facilitates passengers.

In the boarding process, Daxing Airport is equipped with a paperless mode of travel, that is, face-brushing boarding. Passengers do not need to show any certificates, paper boarding passes or electronic boarding passes. They can brush their faces and board the plane, which brings new experiences to passengers. It is particularly worth mentioning that the construction of the terminal area has introduced the traditional garden concept of China, which not only shows the charm of China culture, but also enhances the waiting experience of passengers. The most beautiful place is hidden at the end of the five corridors, with five courtyards-China Garden, Porcelain Garden, Pastoral Garden, Silk Garden and Tea Garden.

In check-in, Daxing Airport cooperates with airlines, and is equipped with more than 4 self-service check-in machines and self-service consignment equipment, with a self-service coverage rate of 8%, ensuring that passengers wait in line for no more than 1 minutes during check-in. In the "paperless" era, secure access only requires brushing your face and ID card. The intelligent passenger security inspection system realizes the functions of passenger self-inspection, automatic integration of passenger re-inspection information, automatic sorting of safe luggage and suspicious luggage, automatic energy saving, automatic return of luggage pallets and so on. The capacity of a single passage can reach 26 people per hour, which is much higher than the traditional 18-person safe passage. It can ensure that the time for passengers to pass the security check does not exceed 5 minutes.

The terminal building of Daxing Airport adopts "multi-point check-in and double-deck take-off". Passengers who take the airport bus, taxi or rail transit can check in at the nearest place. If passengers take the subway, walk out of the subway gate, climb the escalator and enter the first floor of the airport, they can see the indication sign of domestic check-in Check-in counters can be found on both sides of the airport. They can go through the check-in formalities and check their luggage directly, and then go through the security inspection channel, brush their faces and enter the airport safely.
