Cause
Reader Expanders store a limited number of user card records locally, depending on the Offline Operation setting. However, user credentials (such as credential types, biometric or PIN-based data) are stored only in the controller, not in the Reader Expander.
It’s important to note that the term "card" in the Offline Operation feature (as described in the online help and the SX-SRVR Security Expert - Operator Reference Guide) refers specifically to the Card Numbers section [1] of a user record, not the Credentials section [2].
Resolution
The Offline Operation functionality of Reader Expanders supports authentication using Card Numbers only. It does not support authentication using Credential Types when the expander is offline.
