Unfortunately in the country we visit during our holiday, almost exclusively this app is being used. As a result we are not able to visit any restaurant. Hope the developer can resolve this quickly. ### 1/5 — Gives wrong readings *2021-12-01, version 1.3.6* For some reason when using this app on iPhone, it rejects certificates that should pass. When using the app on android, it works fine. ### 1/5 — Does not work? Perhaps lack of standardization between the US and Europe? *2021-09-05, version 1.2.3* Going to Europe soon so i downloaded my official « Digital Covid-19 Vaccine Record. When scanning i got a beep with an error msg of « error at position « 0 » or something similar. Disappointing ### 1/5 — Doesn’t work *2021-08-13, version 1.2.3* I’ve been double vaccinated in Luxembourg and have the certificate in paper form; still, upon scanning the QR code, this app shows “unknown code” for 5 criteria. The only criteria it gets right is my name, DOB, and vaccination date. Unless I’m missing something, that makes this app pretty useless. ## Frequently asked questions about CovidCheck.lu ### What types of EU Digital COVID Certificates can CovidCheck.lu verify?
