Thailand Pass can automatically verify and approve QR codes of digital vaccine certificates from only the following regions at the moment:
The European Union (EU Digital COVID Certificate, or DCC for short)
Singapore (Notαrise)
Support for digital vaccine certificates from the following countries is in progress:
China (International Travel Health Certificate)
India (DIVOC)
Indonesia (PeduliLindungi)
Israel (once it joins the EU’s DCC program)
Malaysia (MySejahtera)
Philippines (VaxCerts)
United States (SMART® Health Card, available in some states)
