A Smart Vaccination Certificate is a digital document that verifies an individual's vaccination status against diseases, such as COVID-19. It is designed to be secure, easily accessible, and can be shared with authorities or organizations that require proof of vaccination for travel, events, or entry into certain venues. These certificates often use technologies like QR codes to ensure authenticity and prevent forgery. Many countries and health organizations, including the World Health Organization, support the use of smart certificates to facilitate safe travel and public health measures while maintaining privacy and data security for individuals.
