That is the technical system to check remotely whether one's test is suitable. In practical terms, the message is that people need to check, go to the reopen EU website and see what the destination rules are, how old a child can be to travel there without a PCR test and is an antigen test acceptable. People need to do that, rather than arrive at the airport and have their certificate refused in advance. Does that make sense?
