Thanks so much for trying to help me! I appreciate it.

I don't have any other NFC cards, unfortunately. But I've tried it on a BQ Aquaris X Pro, Google Pixel 3a and Google Pixel 5 (my current phone).

Also, the app manages to read my ID initially (it displays some personal data of mine) but then it asks me to scan the card another couple times and the third or fourth readout then fails (every single time) and I end up being back to square one (because I need to start the whole authentication process again).

Then it's definitely a case of bad positioning. The app has a limit of three or four attempts, so you're definitely running into that, but if you're seeing the app able to read some data but not reliably, then you don't have the card in the right position.

It may be that while positioning the card you, unknowingly, put it in the right position for a short moment, which allows it to read some data, but by the time it's actually trying to authenticate, you're already out of position.

I don't think that's the case. As I mentioned, the first reads always work. But then, later, when it asks me to hold my ID card against my phone once more (for the final authentication) it always fails.

Again, I have looked up my phone's NFC wiring and I have also tried other phones. The card is in the right place.

You're supposed to hold it in place the entire time, it's not two reads but many continuous ones.
