According to Beijing Health Bao, the remaining four days mean that there are still four days when health information is invalid, and personal health needs to be re-examined after the failure.
Beijing Health Bao is a small tool for individuals to inquire about their health status related to epidemic prevention, which can be used by all personnel in Beijing and those who enter (return to) Beijing. The query results can be used as a reference for your health status related to epidemic prevention in scenes such as returning to work and going in and out of public places. The characteristics of this scheme are: 1, less information collection, only name, ID number and face data are collected, so that Beijing "Health Treasure" can obtain status information, avoiding the problems of multi-collection, repeated collection and excessive collection in epidemic prevention apps and applets. 2. Personal data security. The information provided by users is kept in the Beijing Municipal Government and is only used for this epidemic prevention work. At the same time, through information desensitization and other means, the status information generated on the mobile phone only keeps two digits before and after the surname and ID number, which can protect personal privacy. 3. Easy to operate and use. Beijing "Health Treasure" has few data collected and is easy to fill in and use. In addition, Beijing "Health Bao" adopts an online and offline integrated and relatively independent operation mode. After the health status results are generated by querying in advance, the data within the validity period can be directly obtained. 4. Set the anti-counterfeiting interface. Beijing "Health Bao" adopts the combination of online face recognition and offline on-site verification, and makes full use of static and dynamic anti-counterfeiting means such as face recognition, QR code and circulation effect, which can effectively prevent counterfeiting. 5. "Three-in-one" function.
