Smart cards are typically handled on multiple layers and by multiple components, and for that we would like to provide a brief background to provide context for the following discussion. If you search for a guide how to configure smart cards authentication from scratch in RHEL 7, see Smart Cards section in system-level Authentication Guide. If you search for smart-card support for RHEL 8, see the Smart-card support in RHEL 8 and later article. In addition, it provides information on how to investigate a potential incompatibility between the cards and RHEL. However, because it is not possible to support every smart card available, this document specifies our targeted cards.

In Red Hat Enterprise Linux, we strive to support several popular smart-card types.
