VPass: An Open-Source COVID-19 Vaccine Passport, and Vaccine Hesitancy

The use of technology is one of the keys to combating the covid-19 pandemic. This paper proposes and demonstrates an implementation of a digital vaccine passport /certificate is, called VPass, for taking non-essential services. This passport will represent someone's vaccination status while preserving all personal data safe. The developed application is platform-independent and accessible using any device connected to the internet. This application also keeps an offline copy in a device or a printed copy of a vaccine passport for convenience. A quick response (QR) code will show the COVID-19 vaccination status. All data stored and transmitted between the front (to the end user) and backend (to and from the server) are fully encrypted. This paper presents the technical detail of implementing a digital vaccine passport for COVID-19. This application could also be used for keeping other vaccination records/certificates.
