Blockchain played an important role in this year’s outbreak. Infomacro’s Project Director, Mr. Joseph Chan, shared with us how blockchain can help Guangdong and Macao Health Codes realize cross-border mutual recognition when the backstops of the organizations in the two places are not interconnected and the data does not go out of the country.

Based on FISCO BCOS blockchain technology and WeIdentity distributed digital identity solution, we optimize the electronic operation process and achieve secure and efficient data circulation and authentication by virtue of blockchain’s characteristics of distribution, openness and transparency, non-tampering, non-repudiation and security. In May this year, the Guangdong-Macau Health Code Cross-border Mutual Recognition System was launched, and Infomacro provided technical support for the project. Up to now, the “Guangdong-Macau Health Code Cross-border Mutual Recognition” system has served more than 28 million people for smooth customs clearance, which has effectively assisted the two places to join hands in preventing and controlling epidemics and resuming work and production as soon as possible.
