Laptop fingerprint scanner working with

2 New Member
Hi everyone!

I need to create an app to interact with my laptop fingerprint scanner, for my university project. What should I use to write software for my fingerprint scanner? Any libraries, API, etc. I use lenovo t480 laptop, OS: Ubuntu Linux. There is a fingerprint scanner embedded in it.

lsusb shows my fingerprint scanner as Synaptics Metallica MOH Touch Fingerprint Reader.

I want to process fingerprint -- get, store and check -- programmaticall y, with code on Python, C or C++. If someone provides me information about:
1) how to programmaticall y interact with my laptop fingerprint scanner
2) what API or libraries (python, c or c++) should I use
it will be ideal :)

Lenovo t480 laptop.

This might be contingent upon if the operating system can see it and access it. Not just detect that it is there, but use it. If it can, then search for how the operating system accesses it.

Or, separately it might be contingent upon if you have UEFI anywhere on you laptop (anywhere on it).

If the current OS can not use the fingerprint scanner, then install the original version of the original OS on the laptop and work from there. I expect that the scanner might have an infrared heat detector that detects a finger near to the scanner then takes one or more photographs of what is in front of the scanner. Then a program parses those images into pixels and analyzes those pixels.

If you can override the infrared detector and activate the scanner's camera, then you might be able to use the fingerprint scanner to take pictures of who and what is in front of the laptop any and all time that it is on. If you have UEFI on your laptop then you might be able to run it without the operating system even booting up and take pictures 24 hours a day wherever the laptop goes. To work, to the bathroom, a clothes changing room, to a special secret meeting, etc. It was put there to take pictures automatically.

Tell us how you are doing with this.

I would expect C or almost any version of C++ to work with this.

You might have to study how UEFI actively spys on systems and users by design. There are many versions of UEFI and many are manufacturer designed. They should not be too complicated to work with or replace with your own version.

If your question is to learn how to stop the fingerprint scanner from spying, then I think that the best way is with a soldering iron and/or at least wire cutters. Same with some other things that are on the t480 and other similar laptops.

Dear reader, To work with linked tables is a professional method of working with a frond end and back end mdb. Working with linked tables on a local pc gives an acceptable performance but in case you start working with linked tables on a server (network) the performance will be drastically reduce.

Dear reader, By working with a frond-end and back-end databases with the use of linked tables the performance, if both mdb's are on a local drive is reasonable. But in case the backend is located on a network drive the performance is decreasing drastically.

Hi: Is it possible for me to create/open web application from remote machine other than port 80? And create application directly under virtual web site instead of creating a virtual directory? Because there is a developing server in our company running IIS with multiple web sites, each one has its own port number. In real scenario, no applications will run under virtual directory, but directly under a site. Thanks!

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
