Nitgen fingerprint scanner (NGenBio) UDF


Recommended Posts

Hi guys! :)


I've created this UDF to work with Nitgen fingerprint readers that use NGenBio SDK. I'm working with Hamster DX for testing purposes:



So, the UDF still needs a lot of functionalities but what is already written is enough to do most of the tasks you would want to do with a fingerprint scanner (registering, authentication of a user, identification of a person among many users etc.).

I've put it on GitHub because it will be constantly updated. Also, if you want to help, feel free to clone and send pull requests :D


#include 'NGenBio.au3'

; Enumerate devices
$numberOfDevices = _NEnumerate() ; Enumerate all connected devices

If Not $numberOfDevices Then Exit ; no device connected

_NOpen() ; Open device (no argument = open latest connected device)

; ======================================================================
; Example 1: just get a fingerprint and display the string associated to it

MsgBox(0, "Your fingerprint means:", _NCapture())

; ======================================================================
; Example 2: verification (expecting for a specified person)

; Ask for name (to show how to work with payloads and store info on the fingerprint data)
$sName = InputBox("Test", "Enter your name")

$tmpData = _NEnroll($sName) ; Register a fingerprint (we will have a string to save in DB if we want; $sName will be saved together with the data)

If Not $tmpData Then Exit ; User canceled

$check = _NVerify($tmpData) ; Verify fingerprint (from the string that the registration gave us - it could have come from a database)

If $check Then
    MsgBox(0, '', 'That''s you, ' & $check & "!") ; Correct fingerprint
    MsgBox(0, '', 'That''s not you!') ; Wrong fingerprint

; ======================================================================
; Example 3: identification (expecting for anyone of a group of persons)

; Add the already saved FIR data from the previous example as ID #1
_NSearch_Add($tmpData, 1)

MsgBox(0, "", "You are now user 1. Please call someone else to register (or use different fingers/hand) to test the registration of a second person.")

$secondPersonName = InputBox("Test", "What's the name of the second person?")

; Get data
$secondperson = _NEnroll($secondPersonName)

_NSearch_Add($secondperson, 2)

; Let's ask for the fingerprint to search for
$capture = _NCapture()
$user = _NSearch_Identify($capture)
If $user Then
    MsgBox(0, "", "User: " & $user)
    MsgBox(0, "", "User not found!")

_NClose() ; Close device (no argument = close latest opened device)

Note that you must install NGenBio SDK (although my system is x64, I only had success after installing the x86 version). More details, documentation and link to download the SDK on the readme file.

Get it on Github
