Bureau,

The meaning of the public security bureau.

When swiping an ID card, it is not an alarm. Generally, we only scan the head of the ID card, and then enter the corresponding name and ID number. These data are uploaded to the public security bureau every day. If you see it, the PSB machine at the front desk may just be connected to the security department of your hotel, and then the security department will tell you to send the data to the public security bureau.
