TheBio30R portable semiconductor fingerprint scanner with ARM9 processor. It has the characteristics of fast fingerprint data acquisition speed and excellent image quality. It supports scanning of dry, damp, and rough finger skin and provides a good image quality.

The Bio30R is a small and portable fingerprint scanner developed by ZKTeco. It uses the ARM9 processor and international semiconductor fingerprint sensor. It has the characteristics of fast fingerprint data acquisition speed and excellent image quality. It even supports scanning of dry, damp, and rough finger skin and provides a good image quality.

The ZKTeco FV18 is a multi-biometric reader capable of capturing and processing finger vein and fingerprint biometric data at the same time. The new hardware platform uses ZMM220 core-board with 1.2Ghz CPU. With optimization of both hardware platform and algorithm, FV18 is one of high recognition rate, high security & high speed terminal. The device offers flexibility of both standalone installation and installation with any third-party access control panels which support standard wiegand signal.

The device offers flexibility of both standalone installation and installation with any third-party access control panels which support standard wiegand signal. It has a display of 2.4-inch TFT LCD Color Screen, a fingerprint capacity of 1,000, a vein capacity of 1,000, and an optional card capacity of 5,000 (ID / IC Card / HID Proximity card / iCLASS card). The transaction capacity is 100,000.

The FV18 uses a ZK Finger vein sensor and the ZKFinger V10.0 and ZKFingerVein V3.0 algorithm versions. The communication options include TCP / IP, USB-host, and optional WIFI. The access control interface supports 3rd Party Electric Lock, Door Sensor, Exit Button, Alarm, Doorbell, Wiegand Signal Input and Output, SRB Aux.

In summary, the ZKTeco FV18 is a multi-biometric reader capable of capturing and processing finger vein and fingerprint biometric data at the same time.

There are requirements where you have to integrate a biometric device into your application for things like user authentication, verifying user information, backing up scanned templates into your system database or export it somewhere remotely etc.

Biometric Devices are being used extensively in many corporations through out the world these days. They are widely used in various fields like social insurance, public security, time attendance, fingerprint encryption, embedded systems and many others.

Companies like ZKTeco manufacture biometric access control and Time and Attendance in various shapes and sizes with different set of features per model. They provide a better way of user authentication and security in organizations comparing to the traditional authentication and authorization mechanisms.

Besides establishing a connection to the device, you need to initialize a few more things like the fingerprint image height and width with can be obtained by calling the GetParameters method. It is recommended to use the image size parameters provided by the device instead of using a static height and width.

Yes BitmapFormat.GetBitmap is what you should be using to generate the fingerprint template.

You need to check a few things to get a good image :

1. Check to see if the mfpWidth and mfpHeight matches the one that is retrieved from the code at Line 123 And Line 127 and not some random value that you might be using.

2. Are you successfully obtaining the fingerprint image at Line 577 ?

3. Your FPBuffer length should be the multiple of mfpWidth and mfpHeight.

Hello Ozesh,

Thank you for the source code it worked very well in my Laptop and connected perfect with zk4500 but when i try to connect zk4500 in my PC the application return code -6

Unable to connect with the device! ( Return Code: -6 )

what should i do to solve it?

Hello Mario,

-13 is the error code for possibly an invalid fingerprint template.

1. Check to see if the RegTmp that you are providing to the device is a valid template which you have obtained with 3 successful enrollments.

2. The Zkteco Scanner can only accept a verified template from any zkteco devices and not any other model of devices rather than a Zkteco model.

During the registration process, you can obtain the registered template via the FingerPrintControl class which at that time is retrieved from the systems memory. You can simply save the bitmap as an image file if you want to at this point.

Hello Ozesh,

Thank you for the source code. I have learned a lot from it. I just want to ask if there are any possibilities that those libraries may work with this ZK TX628 model of biometrics device. I am unable to detect any connected device so far. Am I missing anything? Please advice. Thank you.

No, you can`t integrate a ZKTeco Fingerprint scanner in a web application directly.

However, there are other approaches to achieve the web application integration.

Some of them are :

1. Via an intermediate custom application to handle fingerprint enrollments and exporting data to the web api or server.

2. Via the ADMS feature which are available in some of ZKTeco models.

Thank you Ozesh. But I am trying to create a image of the 3 finger images that are merged? Can I save that merged template to my database for a small attendance program I am writing and then match it with a new scanned finger print to verify it?

Hello Rajaram,

I have not got the chance to try it out with the ZK7500 model.

If you have tested it out and if it works for you, Please do inform.

I will include ZK7500 as well as one of the supported devices.

It seems that a higher model of device which uses a higher version of the biometric algorithm supports fingerprint templates from those of a lower one.

However, a lower model device using a lower biometric algorithm might not support a fingerprint template from a higher one.

Yes you can export the enrollments to your database.

But No, it is not possible to verify from database.

The verification requires running a certain algorithm through the fingerprint template,

which can only be done by the device.

I have text box control in aspx page i need to ingrate Magnetic stripe card whenever user swipe card then i need to fetch card information and display on web page so how can i do this?

which approach should use for this??

can you pls help for this??

I try to store and compare the fingerprints of 100,000 people, but there is no device that receives this large number. Is there a solution to store and compare fingerprints from the database or increase the storage space of devices

So if there are thousands of users which I think the device SDRAM cannot hold,then I should write(fingerprint template) to device,compare(identify),erase and write again until I finish comparing or have the exact match.

If you install legacy drivers on Windows 7 or later with Windows Biometric Framework, there is a chance that a future Windows Update could automatically replace the legacy driver with the WBF driver, which could cause your application to not work well. To avoid this possible problem, please be sure to update the SecuGen SDK dll, for example, sgfplib.dll (from FDx SDK Pro).
