Unlocking a phone with a QR Code, possible?

I don’t want biometrics unlock, and 16 character is a pain to type each time.

What I’d like; when unlocking the password will be asked, but it could be possible to enter the password using a QR Code using the pre-unlock camera mode. The password would still be the main way to unlock, the QR would just be an alternative.

Issue; my phone dont want to read a QR Code before unlocking (for obvious security reason).

Does anyone have an idea if it is even possible? If yes, where should I look?

I’m on a Xiaomi 13T Pro.

I think that something like that may be possible with NFC/RFID tags.
