Works well with dry, moist or rough fingerprints.

Then dbl-click the file to install the USB biometric. For superior user feedback, a red "flash" indicates that a fingerprint image has been captured. Digital Persona Fingerprint Reader Select the appropriate link below.

To use, simply place a finger on the reader window and the reader quickly and automatically captures and encrypts the fingerprint image before sending it to TimeDrop for verification. A siliconeĬoating allows it to read a wide range of fingerprints accurately and rapidly regardless of placement angle. Reader utilizes optical fingerprint scanning technology to achieve excellent image quality, a large capture area and superior reliability. ItsĬompact design conserves desk space in enterprises, and its professional, modern appearance looks elegant in all business environments. In the second part of this, I’ll describe how I fixed this problem, using the ManualResetEvent object.The DigitalPersona U.are.U 4500 Fingerprint Reader is a USB peripheral perfect for individual desktop users, as well as multiple users in shared environments. However, because the fingerprint sample might hadn’t been successfully scanned at that point, I got a null reference exception. So control flows straight on after the call to Enroll to the method which tries to create an image. Designed for the Digital Persona U.are.U fingerprint reader. Operating system Windows Xp / Vista / 7 / 8 32 & 64bit.

(For desktop application only) Supports verification : for dekstop application 1 to 1 and 1 to N and for web application only 1 to 1. Scanner.CreateBitmapFile( there was a problem – when designing the implementation, I hadn’t taken account of the fact that the device and SDK is driven by events – so after I start running the program, it’ll happily wait for someone to put their finger on the device screen and won’t block the main thread. Display the fingerprint image is integrated into the application. using ( var scanner = new DigitalPersonaFingerPrintScanner())

#Digitalpersona fingerprint scanner code

This compiled, and I expected to be able to run the code below. This seemed pretty straightforward – I wrote the class below.

Stop capturing a fingerprint from the scanner by calling the StopCapture method from the Capture object.

A parameter of the OnComplete handler contains information about the scanned fingerprint.

After the scan has successfully complete, the OnComplete event is fired.

After placing your finger on the reader, the event OnFingerTouch will be fired.

Begin capturing a fingerprint from the scanner by calling the StartCapture method from the Capture object.

Associate an event handler class with this Capture object, which has handlers for the events:.

Add references to the libraries DPFPDevNET.dll and DPFPShrNET.dll, both of which come with the SDK.

So I decided to write a Console application for the U.are.U 4000B scanner. This SDK comes with a couple of sample Windows applications – but I’ve a personal preference to try to get things to work in a console application, just because it allows me to focus more on the code to get the scanner working (and less on the code to get the Windows app working). Find the best Windows Hello USB fingerprint scanners for your computer. NET SDK available, but make sure that when you are buying the scanner device that you get the SDK as well – it’s possible to purchase these separately. The fingerprint reader on the new keyboard has been designed with subtlety in. To test this, I started looking for other scanners and SDKs – and one candidate which looked very suitable was the digitalPersona U.are.U 4000B sensor. I designed this interface based on the very small amount of knowledge I have of fingerprint scanners and SDKs – so I was still interested to see if this interface would be useful (or even workable) for another scanner and SDK.

I used the Neurotechnology Free Fingerprint Verification SDK with the BioMini hardware.Īs part of the process, I created an interface which allowed me to enroll a fingerprint, and create the image, which defines a good surface for all I want to do at the moment. In a previous post, I used the BioMini fingerprint scanner to generate a bitmap image of a fingerprint.
