The European Commission proposed the EU Digital COVID Certificate for safe travel. It is free of charge, secure, and accessible to all. It is available in digital format and on paper, and it will be proof that a person has been vaccinated against COVID-19, tested negative, or recovered from an infection. The EU Commission has completed the procedures for the certificate launch in June, and the Member States have started implementing it. The EU gateway verifies the security features contained in the QR codes of all certificates. The EU gateway will allow citizens and authorities to be sure that the certificates are authentic. During this process, no personal data is exchanged or retained.
On the other hand, the US has confirmed that there won't be a national app, leaving the choice to states. Some states have banned the apps as examples of government overreach. Different countries are exploring leveraging vaccine certificates. The debate persists on vaccine inequality at a global level, and such vaccine passports further magnify the disparities across populations.
While the adoption of such COVID-19 vaccine passports scales up and travel picks up across geographies, the development community needs to be ready to integrate vaccine passport capability across multiple use cases such as immigration, travel, hospitality, health care, facility management, and much more. There are over a thousand libraries available specifically on COVID-19 vaccine passports as well as good health practices. The kandi collection on COVID-19 Vaccine Passports showcases reusable libraries from the EU Digital COVID Certificate, previously named the EU Digital Green Certificate, and multiple other providers and emerging solutions from the Linux Foundation Public Health (LFPH). The libraries span across issuance, wallets, verification, testing, and analytics of COVID-19 vaccine passports.
