My question is that is it possible to operate fingerprint scanner using raspberry pi in simulink?
if yes, then please guide me.
just an overview.

The overview is:
  • Many fingerprint scanners use undocumented proprietary communications and can only be accessed through the DLL supplied with the scanner. This can be a problem on Raspberry as the DLLs are often MS Windows only
  • A lot of fingerprint scanners calculate minutae on the device and are only able to return those, without being able to return the fingerprint images.
  • There is a linux library that is able to talk to a number of different fingerprint scanners. that library concentrates on getting back minutae rather than on getting back fingerprint images, so examining the code for any one device will give you varying degrees of information about what you might need to do in order to return images for the device. Some of the devices might be quite capable of returning images, but when you look at the code and all you see is that you have to send it (for example) 0xE7 0xEB 0x32 0x99 to get it to return a minutae, then that doesn't give you much clue as to what sequence of bytes you would need to get back an image.
  • Some devices are pretty easy to communicate with, and well documented too.
At this time there is no point going into any kind of detail; at this point the question is much like "Can you control a vehicle using Raspberry Pi"... It's a "Ummm, maybe??" kind of question.

sir according to your answer at present its not possible to do that?
And yes we are trying to control our vehicle using raspberry pi.
basically our aim is to start/ignite our vehicle with fingerprint recognition.

"sir according to your answer at present its not possible to do that?"
No, according to my answer "It depends". For some fingerprint scanners, there is little hope. For some fingerprint scanners it might merely be tiresome to work through to get it to work. For some fingerprint scanners it is easy.
Now if you were to pick a particular fingerprint scanner manufacturer and model, then you can review my past postings about fingerprint scanners to see whether I happened to mention communicating with that particular one.
