The blockchain-based health records system is gradually enabling mainland China to continue tourism across the border into Macau.
This platform makes it easy and fast for tourists from mainland China to confirm their health status upon entering Macau, in just 3 seconds.
Blockchain allows authorities to securely encrypt and record personal health data.
The organization added, "In addition, mutual recognition mechanisms allow seamless transfer of health codes for users without the need to repeatedly fill in personal information on different platforms, which provides convenience and ease of use for travelers across borders."
