Global cardholder management (GCM) is used to synchronize cardholders between independent Security Center installations.
GCM allows you to have a central repository of cardholder information for your entire organization, whether this information is managed from a central office or by individual regional offices. The different locations can have their independent installations share information with a centralized human resource management system.
Each local office continues to manage the employees working at their local office, such as maintaining the employee profiles, photo ID’s, credentials, and so on. For employees that need to travel from site to site, that same information can be shared among all sites within the organization.
