The pcscd service is started by a socket activation.
If there is no connection to the socket, the service is stopped after 60 seconds, because the service is by default started with the --auto-exit option:
-x, --auto-exit pcscd will quit after 60 seconds of inactivity
We have have a service running which has a permanent connection to the pcscd socket, so the pcscd service is running permanently.
We observed that the pcscd service is using more memory, ther longer the service is running on different host:
