Answer Wiki:
There is some commercial APIs to manage fingerprint scanners like those: http://www.griaulebiometrics.com/javadoc/FingerprintSDKJava/ http://www.123id.us/products_developer_cvtsdk.html http://www.biofoundry.com/products/biofoundryFreeTrial.html But I think could be a better way to read about JavaPOS (Point of Service) and JXFS (Java eXtensions for Financial Services). Both technologies are made for Financial Devices like ATMs and kiosk services. It is possible this hardware has fingerprint devices that are compliant with javapos and jxfs. JavaPOS is less complicated than JXFS, but still a some complicated solution. You must read the API specification to be able to write a program to manage one dispositive. Good luck. JavaPOS - www.javapos.com JXFS - www.jxfs.net

For fingerprint recognition you can try GrFinger for Java which is an SDK that you can use to integrate for fingerprint recognition. You can go to their website http://www.grfinger.com for more information and they do have trial versions you can download and install.

Google “bioapi” for many references to the standard for fingerprint (and other biometric) recognition.
Your question indicates that you are not familiar with how fingerprint matching actually works. You may want to research the basics before trying to implement some kind of matching system.
Fingerprints are converted from the initial scanned image (which should be at least 600 dpi in a one-inch by one-inch image to meet FBI standards). Proprietary algorithms are used to convert the image into a set of “minutiae” (plural of minutia).
The minutiae essentially describes the fingerprint in terms of significant features (loops, whorls, splits, and other information about how the ridges and valleys relate to one another) and the minutiae relate each of the individual minutia to the others in terms of relative distance and orientation.
The algorithms that do the minutiae conversion and matching are generally proprietary, so that each of the commercial companies that sell these systems to government agencies can try to claim that their matching system works better than the others.

With the BioAPI, the code to “enroll” prints and “match” prints is pretty simple.

Trying to write your own code to transform a scanned image into minutiae, or to try to do your own minutiae matching would be a job for a seriously advanced programmer with a PHD in math, physics, and/or biometric engineering.
