This project aims on reverse engineering protocol of Validity 138a:0090, 138a:0091, 138a:0094, 138a:0097 fingerprint readers, creating specification and FLOSS libfprint driver.

- spec.md - Specification draft, the main work goes here right now.
- dissector.lua - Wireshark dissector for decrypting communication after key exchange.
- libfprint directory - libfprint repo with this driver integrated
- prototype - Standalone prototype(extremly ugly code, would be completly rewritten for driver)
Prototype testers are needed, please share your result and join us in our Gitter.
