# ebkn-m61-protocol: reconstructing biometric terminal communications

> ebkn-m61-protocol documents communication with EBKN and Realand BioFace M61 biometric access terminals and supplies a Python reference listener. Its specifications cover WebSocket with XML messages, FkWeb HTTP posts with JSON, and raw TCP XML streaming, including attendance events and supported command exchanges.
