Does the fingerprint reader have an API? How does it communicate with the world? USB? Serial Port? Proprietary interface? What is its output? Text? Binary image?

Rails is a Web application toolkit, Ruby is a general purpose programming language. Between the two, you may be able to lash together an interface, such that an operator sitting at a Web application could press a button, instruct the scanee to "swipe your finger" and receive back a structured data package (maybe an image of the fingerprint) that the Web application would accept as input. You might even be able to get an unattended station to work (scanning a finger initiates the storage of data). But you have to answer a whole lot of other questions first.
