Decription
This component allows to read the fingerprint through a biometric reader like
distributed from the PreciseBiometrics™. With this component is possible
to write applications that demand the reading of the fingerprint. The new
version able to compare the external file fingerprint image from a database
archive, include the VB sample of to use it.
Requirements
This component requires Visual Basic 6.0 Run-Time and PreciseBiometrics™
Library. The component can be used with any development environment that
supports its. This control depends on the MSVBVM60.DLL for VS6 and PB.DLL
library (installed with
Reader Device Driver) which must be installed in the Windows™
system directory.
Hardware supported
Precise Biometrics 100 SC Readers
Precise Biometrics 100 AX Readers
Precise Biometrics 100 MC Readers
GemPlus GemPC-Touch 430 Readers
This version match only 10 fingerprint in 1 second.
Important Notice
Precise Biometrics(tm) has defined at EOL (End Of Life) the fingerprint scan reader of the PB100 SC/AX/MC series.
Please consider that we will NOT be able to support further our ActiveX with the new hardware produced.
If you want to use the new readers from Precise Biometrics, please, DON'T BUY OUR SOFTWARE, as this
software is NOT compatible with the new hardware. We do apologize for the inconvenient.

Visual Basic Sample
on Form_Load Event:
FingerPrint1.Interval = 1000
on FingerPrint_FingerIn Event:
Save a image with current fingerprint in reader:
With FingerPrint1
aRaw = .RawDataB ' get raw data
Set pic = RawToPicture(aRaw) '
convert to image
.Save pic, "MyFingerP.gif" ' save image
End With
Compare previous saved image with current fingerprint in reader:
With FingerPrint1
aTemplate = .TemplateDataB ' get template data
Set pic = .Load("MyFingerP.gif") '
get fingerprint image from file
aRaw = .PictureToRaw(pic) ' convert image to raw data
' verify current fingerprint with fingerprint image loaded from
file
If .VerifyFingerEx(aTemplate, aRaw) Then
MsgBox "The fingerprint picture is same of the
current fingerprint in the reader."
Else
MsgBox "Unrecognized fingerprint."
End If
End With
