WINBIO_ANSI_381_POS Fingerprint Constants
The following constants can be used to specify the fingers scanned by a sensor:
- **WINBIO\_ANSI\_381\_POS\_UNKNOWN**
**WINBIO\_ANSI\_381\_POS\_RH\_THUMB**
**WINBIO\_ANSI\_381\_POS\_RH\_INDEX\_FINGER**
**WINBIO\_ANSI\_381\_POS\_RH\_MIDDLE\_FINGER**
**WINBIO\_ANSI\_381\_POS\_RH\_RING\_FINGER**
**WINBIO\_ANSI\_381\_POS\_RH\_LITTLE\_FINGER**
**WINBIO\_ANSI\_381\_POS\_LH\_THUMB**
**WINBIO\_ANSI\_381\_POS\_LH\_INDEX\_FINGER**
**WINBIO\_ANSI\_381\_POS\_LH\_MIDDLE\_FINGER**
**WINBIO\_ANSI\_381\_POS\_LH\_RING\_FINGER**
**WINBIO\_ANSI\_381\_POS\_LH\_LITTLE\_FINGER**
**WINBIO\_ANSI\_381\_POS\_RH\_FOUR\_FINGERS**
**WINBIO\_ANSI\_381\_POS\_LH\_FOUR\_FINGERS**
**WINBIO\_ANSI\_381\_POS\_TWO\_THUMBS**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_01**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_02**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_03**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_04**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_05**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_06**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_07**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_08**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_09**
**WINBIO\_FINGER\_UNSPECIFIED\_POS\_10**
Remarks
The WINBIO_FINGER_UNSPECIFIED_POS_* constants are not part of the ANSI 381 specification. You can use these constants to enroll up to ten fingers (per account SID) that have no associated position information.
Important
Do not attempt to validate fingerprint constant values. The Windows Biometrics Service will validate supplied fingerprint constant values before passing them through to your implementation.
