The International Air Transport Association (IATA) has come out in support of making the EU Digital COVID Certificate (DCC) the global standard for digital vaccine certificates. Conrad Clifford, deputy director general, said that in the absence of a single global standard for digital vaccine certificates, the DCC should serve as a blueprint for other nations looking to implement digital vaccination certificates to help facilitate travel and its associated economic benefits. The EU DCC, said IATA, meets several key criteria that have been identified as important if a digital vaccination certificate is to be effective:

• Format: The DCC has the flexibility to be used in both paper and digital formats.

• QR code: The DCC QR code can be included in both digital and paper formats. It contains essential information as well as a digital signature to make sure the certificate is authentic.

• Verification and authentication: The European Commission has built a gateway through which the encrypted data used to sign DCCs and required to authenticate certificate signatures can be distributed across the EU.

The EU DCC is implemented in the 27 EU member states, and a number of reciprocal agreements have been reached with other states’ own vaccination certificates, including Switzerland, Turkey and Ukraine. The DCC, said IATA, is “an excellent model” as it is consistent with the latest World Health Organization guidance and is fully supported by IATA Travel Pass.
