FAQ
What is VDS-NC Checker?
VDS-NC Checker is an application developed by the Australian Passport Office to authenticate Visible Digital Seal for Non-Constrained Environments (VDS-NC) certificates. These are digital health certificates, like vaccination records, that use ICAO standards for security.
How does VDS-NC Checker work?
The app uses the ICAO Public Key Infrastructure (PKI) to scan a 2D barcode. It determines if the code is a VDS-NC, if it was issued by the claimed authority, and if it has been altered, providing a verification status.
What information does VDS-NC Checker display?
If a QR code is authenticated as a VDS-NC, the app displays the most important information from the certificate, including the holder’s biodata and COVID-19 immunizations. Users can also opt to view the complete dataset.
Which countries' VDS-NC certificates can VDS-NC Checker authenticate?
Currently, VDS-NC Checker authenticates VDS-NC vaccination certificates issued by Australia, Japan, Nauru, Tuvalu, and Samoa. Future updates will expand support for certificates from other countries.
Can VDS-NC Checker authenticate certificates offline?
Yes, VDS-NC certificates leverage the ePassport public key infrastructure (PKI) and can be authenticated offline using keys available from the ICAO Public Key Directory and other published Master Lists.

VDS-NC Checker is available for iPhone, iPad, and iPod devices. It requires iOS and is designed for mobile use.
