Strange, installed an electric door lock with NFC. Can open it... weird.

admin

I bought an IC electric door lock, which said it could add NFC to the phone.n
Then it turns out that I can actually do it with iOS free use of mobile apps, and I got a [Xiaoxiang Card·Public Transportation Card]. After using my management card to swipe it, I was able to open it.n
I set up my wife's mobile phone with a Xiaoxiang Card without adding it first, but it still works when swiped in.
