Ensure your compiler's Target CPU is explicitly assigned to match the DLL architecture. If using the 32-bit SDK variant, switch your project compilation target away from Any CPU to x86 . Protected Memory Access Violations Integrating employee fingerprint clock-in/clock-out systems
: Maintain static singletons for your hardware handlers. Use the centralized zkfp2 object classes uniformly across your thread scopes rather than re-instantiating the driver class. Ensure your image buffers match exact structural constants specified by the hardware's image resolution ( _fpWidth and _fpHeight ). println!("✅ Proof verified without revealing preimage")
