Fingerprint authentication for a django website

I am looking to add a layer of security to my website by incorporating fingerprint authentication. This project is for personal use, and while I may have a rough idea of what I'm looking for, I am open to suggestions for the best software for this purpose. The security level I am looking for is intermediate, providing my customers with an extra level of assurance that their information is safe. I am working with a Django platform, so I need an expert to help me reach my goals.
