Fingerprint management application task link behavior
Updated: August 23, 2010
This topic describes fingerprint management application (FMA) task link behavior
This information applies to the following operating systems:
- Windows Server 2008 R2
- Windows 7
If the FMA task links are shown, their behavior depends on the following factors:
- Number of biometric unit compatibility groups available in the system pool
- Number of FMAs registered
- Number of available devices that work with the FMA
- Presence of a global FMA
A biometric unit compatibility group is a set of sensors that each use instances of the same sensor adapter, matching engine, and storage adapter. If a user enrolls for one sensor in the group, then that user is enrolled for all sensors in the group.
A sensor can have an FMA registered for it specifically and there can also be a global FMA registered for all sensors. The FMA registered for a specific sensor is used only when there is no global FMA registered. If a global FMA is registered, then the global FMA is always run regardless of how many device-specific FMAs are registered.
It is possible to configure the system improperly, and get into a state where there is no global FMA registered and no device-specific FMA registered. You should avoid this situation by always registering a device-specific FMA.
