There is some commercial APIs to manage fingerprint scanners like those:
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.
