The fingerprint sensor captures an image of the finger and relays it to the DSP. The DSP runs image enhancement, template extraction and identification and/or authentication algorithms to match the captured image against stored fingerprint templates. On a successful match, the DSP sends a signal across the RS232 standard to authorize access to the secured asset along with using some form of visual or audio signal to let the user and the system know that the user is verified. On a failed match, some form of visual or audio signal can be generated using the DSP to alert the users and the administrators.
