I need to read the user's fingerprint from my application.
What I really want is a simple SDK that works with a lot of inexpensive fingerprint readers but I can deal with something that works only with one specific model if that model is cheap and available worldwide.
And it has to be royalty-free, I can pay for a development license but if I have to pay for each installation I just can't use it.
What I'm doing has no relation to login or encryption, so the software included with the reader will probably be useless to me.

VeriFinger SDK is based on VeriFinger fingerprint recognition technology and is intended for biometric systems developers and integrators. The SDK allows rapid development of biometric applications using functionality from the VeriFinger algorithm for Microsoft Windows, Linux, macOS, iOS and Android.
Using Forged Fingerprints to Crack the Security If the hacker can't get an unsecured image, they can choose to create a fingerprint instead. This trick involves getting a hold of the target's prints and recreating them to bypass the scanner.
The biometric API provides three basic functions: Match biometric information on-card. Enroll users off-card and transfer their information on-card. Verify the user in a sequence of off-card and on-card interactions.
The report says a fingerprint scanner can be "hacked" by using a picture of the target's fingerprint, creating a negative in Photoshop, printing the resulting image, and then putting some wood glue on top of the imitated fingerprint so it can be used to trick many commercial scanners.
There is no standard API for reading fingerprint data as far as I'm aware since it is a fairly new field and there's no standard way of doing it. Each manufacturer will provide their own API for reading the hardware. The API could just be IO specification to the hardware and there's no library whatsoever, which makes things a bit trickier. This is down to two factors. The first is that finger print readers are used in many applications - custom hardware, embedded systems through to PC authentication and beyond. Providing software for all those different systems would not be viable from the manufacturers point of view. Secondly, each manufacturer uses a different approach to reading and processing the captured images which would make a common API problematic.
