I checked in. I didn't have an ID card, but I also scanned my face when I checked in. Are you connected to the public security system?

I checked in. I don't have an ID card, but I registered. I brushed my face and accessed the public security system.

Because the hotel will access the public security population database, the occupants only need to "brush their faces", and the public security database will compare and confirm their identities, thus effectively helping passengers to check in.

The equipment used for hotel code scanning is also a special equipment authorized by the public security organ. The collected information is directly connected to the public security database, saving time and effort.
