Maybe there is a dedicated device like that, but it seems to me that a simple laptop and USB fingerprint scanner would do the job.
There shouldn't be a second conversion process involved, the scanning software should take care of how the image is recorded. And, while my programming training is old and never that good, it seems to me that if the software is not instantly available it's very simple to create or re-create.[/qu

![:hello: :hello:]()
my aim actually is to prepare a portable finger print module capable of storing fingerprints of 100 students
so as a portable device it have sources like flip flops or micro controllers mainly
its highly impossible to store a finger print occupying some kbs in them
and hence i have gone for compression techniques or conversion techniques
i) compression involves image processing
ii) conversion also occurs through image processing ie from pixels to grey or binary codes for effective storage of image with less space occupying
but i am not sure of the techniques involved in this compression can be done by using SPIHT technique(software) or else we can go for threshold voltage concept
can u suggest the best for practical application in this regard
