Question: Hello! I’m currently adding biometrics to the registration app, mainly in the form of fingerprint capture and enrolment. Using the superb guide from @mogoodrich here, I successfully implemented a lightweight app for fingerprint scanning and matching, relying on the SecuGen SDK. I built a module that implements the BiometricEngine interface, and interacts via REST APIs with the aforementioned fingerprint app.
This brings me to the integration with the registration app. In System Administration → Manage Apps → Add App Definition, I added json that included the fingerprint widget, as well as the default patient form fields (name, address, phone number etc).
See the json on pastebin here.
It seems to work fine, but when I open the biometric section of the form in the registration app, I get this:
The big purple button is unresponsive. I currently do not have any fingerprint scanners connected.
Additionally, I noticed this in the tomcat logs, but I’m not sure if it’s the cause
Once again here is my json configuration for the fingerprint widget.
registrationapp version: 1.24.0 registrationcore version: 1.11.0
Thank you very much for the help. I’m happy to provide any further information.
