In a previous post, I used the BioMini fingerprint scanner to generate a bitmap image of a fingerprint. I used the Neurotechnology Free Fingerprint Verification SDK with the BioMini hardware.

As 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. 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.
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. This has a .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.
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). So I decided to write a Console application for the U.are.U 4000B scanner.
This video shows the standard procedure when using Fingerprint SDK with PHP + Javascript sample. This is just an expected behavior.Visit http://www.griaulebi. A wide variety of php fingerprint scanner options are available to you, such as stock. You can also choose from time & attendance, waterproof / weatherproof, and touch screen php fingerprint scanner, as well as from 1-year php fingerprint scanner, and whether php fingerprint scanner is usb.
Crossmatch single fingerprint scanner newer model is certified with STQC UIDAI and meant for using in Aadhaar related verification, validation and authentication. Its part number is Precision PBABAS300 it comes with 1 year of RD Service and warranty. This product will not come with CD, software program or manuals, Only typically the device will be shipped. The combination of a Crossmatch Digital Persona Eikon Touch 510 Fingerprint Reader with typically the DigitalPersona Identity Engine creates an unmatched ability in order to recognize even the most difficult fingerprints. This product will not come with CD, software program.
There are a few simple steps:
- Add references to the libraries DPFPDevNET.dll and DPFPShrNET.dll, both of which come with the SDK;
- Instantiate a DPFP.Capture.Capture object;
- Associate an event handler class with this Capture object, which has handlers for the events:
- OnComplete;
- OnFingerGone;
- OnFingerTouch;
- OnReaderConnect;
- OnReaderDisconnect;
- OnSampleQuality.
- Begin capturing a fingerprint from the scanner by calling the StartCapture method from the Capture object.
- After placing your finger on the reader, the event OnFingerTouch will be fired.
- After the scan has successfully complete, the OnComplete event is fired.
- A parameter of the OnComplete handler contains information about the scanned fingerprint.
- Stop capturing a fingerprint from the scanner by calling the StopCapture method from the Capture object.
This seemed pretty straightforward – I wrote the class below.
And this allowed me to write the following simple program.
So this is a good start – I was able to capture a fingerprint and save it to my desktop. However, this implementation doesn’t use the interface I designed last time, which has separate methods for Enroll and CreateBitmapFile. I refactored the code slightly to implement this interface.
This compiled, and I expected to be able to run the code below.

Unfortunately 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. So control flows straight on after the call to Enroll to the method which tries to create an image. However, because the fingerprint sample might hadn’t been successfully scanned at that point, I got a null reference exception.
In the second part of this, I’ll describe how I fixed this problem, using the ManualResetEvent object.
FlexCode SDK is simple and easy to use in accordance with the demands of your application needs. FlexCode SDK provides more advancedsolution, suitable for those who need more freedom in creative. The functions in FlexCode SDK are not too basic, the functions concept are instant, you simply call the functions required for registering and verify fingerprints then FlexCode SDK will do registration process and verification process without you need to be directly involved in it. The registration process will produce a fingerprint template in a text format that is easy to be stored and distributed. When you want to identify a finger, the templates are used to compare the fingerprints scanned. You will get the results of the verification whether the same finger or not. FlexCode SDK greatly save your time to integrate fingerprint technology into any application required.
FlexCode SDK license attach to the device. 1 license for 1 device. License cost is US$ 35. Please see our video 'How to buy'.
The advantages and flexibility you get on FlexCode SDK:Digital Persona Fingerprint Software
- Template in a text format that is easily stored and distributed. Template secure because it is encrypted with your own password.
- The balance between speed and accuracy average of up to 200 fingerprint templates per second.
- Display the fingerprint image is integrated into the application. (For desktop application only)
- Supports verification : for dekstop application 1 to 1 and 1 to N and for web application only 1 to 1.
- Operating system Windows Xp / Vista / 7 / 8 32 & 64bit.
- Designed for the Digital Persona U.are.U fingerprint reader. Compatible devices are U.are.U 4000B and U.are.U 4500.
