2.11. The PC Card Daemon
The
pcscd daemon is used to manage connections to PC and SC smart card readers. Although pcscd is usually a low priority task, it can often use more CPU than any other daemon. This additional background noise can lead to higher pre-emption costs to real-time tasks and other undesirable impacts on determinism.
