From May, Macau’s blockchain-powered medical data system has recognized ID codes of the Guangdong health system on the mainland, allowing mainland Chinese tourists to verify their health status using the DLT-powered system when entering the autonomous region.
To date, more than 17 million tourists have cleared customs between Macau and China’s mainland using Macau’s blockchain health code. The announcement boasts that it takes just 100 seconds for mainland Chinese to generate a Guangdong health code for the first time, and roughly three seconds for future health verification when traveling through customs:
“The establishment of Macau blockchain health code and the mutual recognition mechanism with Guangdong health code greatly improves the efficiency and accuracy of information verification across borders. It proves to be an effective solution to bring travel between Chinese mainland and Macau back to normal.”
The system encrypts medical data to the FISCO BCOS consortium blockchain, which is immutably signed by issuing authorities. WeChat’s “WeIdentity” solution is used to transfer data between Macau and Guangdong in adherence to Macau’s data protection regulations.
Macau’s health code system was introduced in response to the coronavirus pandemic, which saw the territory suspend travel from mainland China in January.
The blockchain-powered “digital health passport” was developed by the Singaporean government-owned investment firm SGInnovate and local startup Accredify. The firms began working on the system in May to increase the efficiency of workflows among medical workers fighting the pandemic.
Last week, local media revealed that the Chinese island province of Hainan is also seeking to trial a blockchain-powered rewards program to boost tourism as China’s economy reopens. Hainan was selected last year to host a regulatory sandbox for blockchain innovation.
