I can add my campus card normally, but unable to use it due to the system does not opening the nfsee app when I swipe it. I looked into the NFC settings and found that nfsee app was not recognized correctly, so unable to set it default, moreover unable to use the app function normally.

Currently, we are using the foreground reader mode, which is not compatible with background polling.
BTW, the screenshot you provided is for card emulation. It's a totally different use case.

But when I try to use the app in foreground and swipe to the card reader, the app automatically jumps to the system preinstalled wallet app, and unable function normally.

That's right. NFSee and the used NFC library (flutter_nfc_kit) leverage Foreground Dispatch. Therefore, you have to click the Polling button before tapping your card.

I already added it successfully, I am going to use it to swipe the door & ATU（阿荼）and canteen meal fee. Just replace the campus card with phone.

Unfortunately, NFSee is a tool for reading cards only. BTW, emulating the Tsinghua Campus Card is impossible.
