I needed to be able to integrate with some biometric devices for authentication, but the template data needed to be stored on a server, to enable sharing between locations.
It makes sense to associate a fingerprint template, for instance, with a django user. We can then get these templates at the client end, and use this information to authenticate there.
Note, this authentication is not for the django application, but just for a local application which happens to use the django users table.
To install, add 'biometrics' to your INSTALLED_APPS.
You will then have an attribute on your User class, fingerprint_templates, that contains a list of fingerprint templates associated with this user.
A typical use might be to download a list of valid users when the program starts, which are then used to authenticate.
