That is not how I read the situation. I believe the PCR which is the gold standard of testing will still be used, just not on every single passenger. ie. say a negative rapid test result is achieved but the passenger is displaying flu like symptoms - they will then have to have a PCR test, or say there is a positive rapid test result, that will have to be followed up with a PCR test to verify. And if a passenger didn't bring a rapid test kit with them, then they will have to endure the full PCR testing process.
