Beijing Health Bao can't use the rear camera. The portrait used in the rear camera is basically reversed, which is not consistent with the photo on the ID card. There will be mistakes in this case, so you can't switch to a rear camera.
In this case, the human eye can't directly identify it, and it is easy to identify the error. In this case, the class is easily blocked and can't be done. General health system identification requires the use of a front camera.
Beijing Health Treasure Operation Guide:
Open WeChat and Alipay, search for the "Beijing Health Treasure" applet, enter your name and ID number when using it for the first time, conduct face recognition, and inquire about your health status. The query results include "centralized observation", "home observation" and "nothing unusual".
They are marked with red, yellow and green and can be viewed on the status results page. The status information generated on the mobile phone only keeps two digits before and after the "surname" and ID number, which realizes the double minimization of data collection and personal privacy.
In order to minimize the risk of peak congestion, it is strongly recommended that you use Health Bao to get healthy before going out every day, and don't passively open it when checking. Health Bao will cache the health status obtained by users when they use it for the first time every day on the mobile phone to ensure safe desensitization, which is effective within 24 hours. Even when there is no network, the self-check function can check the health status of the user on that day.
