About COOV
​Complete Privacy
Protection

COOV perfectly protects users' privacy by
utilizing the blockchain technology to provide
immutable digital credentials and to verify
them without a traceable server.

Cross-Verification of
Digital Credentials

Users can present their digital credentials to interested
parties, and also verify someone else's credentials by
scanning their QR code.

Include Additional Information

Aside from their COVID-19 vaccination credentials,
users can also provide additional information ​(name,
date of birth, nationality, passport number, photo, etc.)
to interested parties.

Multi-purpose Credential
Verification

In addition to providing vaccination credentials for
COVID-19, COOV can also provide other credentials,
including the age classification for verifying whether
the user is a minor or an adult.

International Compatibility

PASS-INFRA, the global vaccination verification and
management solution that COOV is
based on, is available for governments and institutions around
the world to use for free. Because of PASS INFRA's international compatibility,
COOV users' COVID-19 vaccination credentials can be
verified in other countries as well.
