We used the BinaxNow to return from Spain in December. It's very simple. We did it early in the morning so we could enjoy the rest of the day. You download the Navica app and register. From there they connect you to emed and you do the test supervised. The results only take 15 mins. We immediately received an email with the results. We took a print screen on our cell and uploaded the photo to the VeriFly app and answered all the questions, it was worthless because we were still not able to check in online. But it did get us to a faster check in line at the airport.
