As Hong Kong and China prepare to resume quarantine-free travel, Hong Kong’s government will introduce a Beijing-style health code from December 10

The Hong Kong Health Code will take note of a user’s real name, address and identification number.

The voluntary app is designed to be compatible with systems in both Macau and Guangdong provinces in southern China.

In mainland China, a mandatory health code dictates where residents and visitors can travel to and from, sharing real-time data with authorities.

The introduction of this health code system in Hong Kong will allow Chinese officials to open back up the nation’s borders with the city-state.

Hong Kong’s chief information officer also says records “won’t be transferred to mainland authorities unless the person is infected or has been a close contact”.
