Most fingerprint readers do not output a raw image by default. They output a data stream that is often already processed—converted from the raw capacitive or optical signals into a digital raster, and frequently compressed to facilitate USB 2.0 transmission speeds. libzkfpdll handles this initial handshake.

libzkfpdll is a native library (DLL) commonly associated with ZKTeco fingerprint devices and SDKs. It implements functions for interacting with fingerprint sensors: initializing devices, enrolling fingerprints, capturing templates, verifying and matching templates, and managing device-level operations (e.g., LED, buzzer, device info). Developers use libzkfpdll in desktop applications (often Windows) to add biometric authentication and identification features.
