fingerprint device constraint

due to the constrain of the device, i need to change something on my system to make it work..
for now, the sdk for verifying user is not available. Therefore, i'm going to brief through the new system.

the panel clinic side will be changed to offline mode as the fingerprint sdk only support windows application instead of web based application. Logically, i'll change the web-based sites that i have built to windows application, then from there, i'll get the try integrating the fingerprint with it. There will be registering of staff and family members in the utm. But no fingerprint will be registered there. The fingerprint will be registered by the clinic staff.

When a staff go to a clinic, they provide a staffID which the utm admin will check with the utm database. If validated, enroll process will begin. Then for the second visit, the staff will only need to scan their fingerprint to authenticate their identity. This process is needed as there is constraint of the fingerprint device.

The device only allowed verification within the device itself, i could not extract out the fingerprint template out of the device as it has been blocked to do so. I also hope that i could use the available sdk to extract out the staffID instead of the boolean value that only can be returned to the windows application. This is important as staffID will be used as parameter to get user's profile and proceed to the billing page.
