Biometic in compact framework

[ayrookuzhy]

hi friends,

Can u people provide some idea and sample code how to develop the
biometric application using vb.net in pocket pc.

If you provide some tips that will be helpful for me.

Take a look at this guys web site he has all sorts of things that might
help.

"Biometric" is a pretty broad term. There's no single set of tips that
would make sense for every sort of biometric identification. Most devices
for things like hand geometry, fingerprint reading, etc. will have APIs that
you'd use to write your program. I'm not aware of any generalized API that
would work with devices from multiple manufacturers. Our fingerprint reader
has a set of serial commands that you send it, which shouldn't be any
problem with managed code, or you can use an API DLL for it, which you can
P/Invoke from managed code.

Dear Paul,

Thanks for the reply. My requirement is to add the fingure print image
to database and check fingure print login in my compact framework
application. can you please give a sample code for this purpose. which
Api dll i should use.

Thanks once again too.

So, you'll have to get the image from the biometric device. The format of
such 'images' is not standardized, nor is it always an 'image' in the sense
of 'picture'. Capacitive detectors don't make a picture and most readers
don't store the full image, as it's large and not particularly useful. They
store the information they need to make a match.

As I clearly stated before, which device you are using will determine what
you can use. THERE IS NO STANDARD Microsoft API FOR BIOMETRIC DEVICE
ACCESS.

Check with the fingerprint reader hardware OEM. If any API exists, it will
come from them.

better question would be - which biometric providers are capable of
..netcf and how we can access their api ?
