Brief introduction of "exposure notice"

Apple and Google, two major mobile phones and system competitors, came together and joined the "exposure notice" of iOS and Android operating systems. Exposure notification refers to the ability to determine whether a user may have contacted a patient who claims to be infected with coronavirus pneumonia-19 by using a rotating random Bluetooth identifier without infringing privacy.

The mobile phone must always turn on Bluetooth to remain active. If both parties in close contact are using travel cards, you and the other party's mobile phone will record the contact events through Bluetooth interaction, and the contact time and distance will be encrypted and stored in their respective mobile phones.

If the contact is not infected with COVID-19 virus within 14 days, the data will be automatically cleared; When the other party is diagnosed as a confirmed or suspected patient in COVID-19, with the consent of the other party, his encrypted ID will be uploaded to the server, and your mobile phone will receive an APP and SMS reminder as soon as possible.
