QR code based travel being considered...
https://www.scmp.com/news/hong-kong/...wn-health-code“There will be a Hong Kong health code based on Covid-19 test results. The government is discussing with Guangdong and Macau authorities to ensure they recognise our test results and health codes for exemptions from quarantine requirements on their sides and vice versa. There will not be any transfer of personal data among governments,†the source said.
Before applying for a QR health code, a person will have to undergo a Covid-19 test. He will either have to send his saliva sample to a hospital via delivery services or submit it in person. Results will be available within 12 to 24 hours in private hospitals.
The hospitals will then directly input the results on an online platform of the government, while also sharing them with the applicant.
Upon getting a coronavirus-negative result, the applicant will be eligible to apply for a QR health code by inputting his personal information on an online system. Once approved, the code can be shown from smartphones while crossing the borders. A QR code will be valid for around seven days.
