17M Chinese tourists verify health using blockchain to visit Macau

Interoperability between Macau's blockchain-powered medical data system and mainland Chinese health codes allowed tourism between the jurisdictions to recommence.

Chinese non-profit blockchain consortium FISCO BCOS, reports that blockchain-based health records have successfully enabled China to resume mainland tourism to Macau.

From May, Macau's blockchain-powered medical data system has recognized the ID codes of the Guangdong health system of 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 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.

At the end of September, it was announced that the system had been used to verify coronavirus discharge records more than 1.5 million times.
