>Retrieval of lab results and verification process
>The Corona-Warn-App Server uses the TAN to verify the authenticity (Figure 3, steps 13-15) of the submission with the Verification Server. The TAN is consumed by the Verification Server and becomes invalid (Figure 3, step 14)
Question:
Some people do carry two phones and switch them regularly, eg one work phone one private phone. AFAIK only one TAN comes with the result is invalid after on use, which indeed should be the case. But how can we allow people to mark two phones and their sent IDs as infected with on test result?
