The Vaccination Certificate Verification Application (VCV) is a Malaysian Government application to verify the COVID-19 vaccination certificate issued by the Malaysian government and the vaccination certificates of other countries recognized by the Malaysian government. VCV users can verify the vaccination certificate by scanning an optical QR code displayed on the MySejahtera application or a certificate downloaded as an electronic document or printed on paper.
VCV verifies two categories of vaccination certificate QR codes containing:-
i) URL of a trusted server that points to identity and vaccination information. This verification requires internet connectivity.
ii) Identity and vaccination information with a digital signature issued by a trusted entity. For this verification internet connectivity is not required because the list of trusted public keys is stored in VCV.
VCV will be updated periodically to maintain the list of trusted servers and trusted public keys.
VCV will display the result of vaccination certificate verification. Identity and vaccination information is displayed only if the vaccination certificate is valid. VCV is designed to not retain certificate information as a privacy protective measure.

The present version of this application is able to verify certificates from the following countries:-
-Malaysia
-Singapore (Online QR & Offline QR)
-Thailand
