A digital Covid vaccination passport is being jointly developed by a group of health and technology companies who anticipate that governments, airlines and other firms will soon start asking people for proof that they have been inoculated.

A coalition known as the Vaccination Credential Initiative — which includes Microsoft, Salesforce and Oracle, as well as U.S. health care non-profit Mayo Clinic — was announced on Thursday.

The VCI said it wants to develop technology that enables individuals to obtain an encrypted digital copy of their immunization credentials that can be stored in a digital wallet of their choice, such as the Apple Wallet or Google Pay.
