I've summarized and tested many things to make it work. But I can't achieve proper behavior when my system is connected in autonomy. Using serial communication it seems like it never «freezes». But when the system is autonomous using a Vin/GND and only propagating the signal to pin 7 it doesn't work after some minutes.
Here is my sketch, I've tried to remove the RST pin as suggested in many places and fallback to software behavior. Also tried MFRCV2 library, which uses the same principle.
Hello,
I've summarized and tested many things to make it work. But I can't achieve proper behavior when my system is connected in autonomy. Using serial communication it seems like it never «freezes».

Here is a copy of my code : https://github.com/OSSLibraries/Arduino_MFRC522v2/issues/28#issuecomment-1807913965
I can't understand why it doesn't work.
