When did the public security system of face recognition in Beijing hotels start?

The public security system of face recognition in Beijing hotels began on 20 12. In the early stage, the hotel installed the client to upload the guest check-in information in real time, and then swiped the ID card. In order to solve the problem of non-ID check-in, a face recognition assistant device was installed. Only when the ID card and face recognition match can the guest check in successfully.
