And I tried to read the tag from a card written by the iOS app, and nothing happened, Launchbox didn’t launch the game.

does it work if you use write to tag from the web ui instead of from launchbox?

I tried to use write from the ui, and sadly it doesn't work: "no readers with write capability connected"

Probably an issue with Windows ACR122U reader driver

I don't really know, but this Launchbox third party app/plugin is working great with the same ACR122U reader/writer:

It writes to NFC cards and reads them flawlessly, that's strange.

Ah that actually confirms it I think thank you. So the thing is the ACR122 on windows has a special driver that I wrote in like a weekend. It was basically the bare minimum to get it working and doesn't handle any edge cases

I don't have an exact ETA but I'm getting some samples on soon of a different NFC reader which uses the same driver and I am planning to add proper support for it, which should also improve the ACR122. I will update here when I've made some progress
