Four Finger Fingerprint Collector

Ultra high image quality: The optical fingerprint distortion free transformation system provides high fidelity fingerprint images, which is beneficial for extraction.





Powerful collection capability: With a large collection window size, it integrates ten finger flat, single finger flat, and single finger rolling collection into one.





Fast capture speed: The four finger scanner captures at least 10 frames and supports real-time finger detection.





Strong adaptability: suitable for various types of fingerprints, automatically removing residual fingerprint traces and halo effects, thereby achieving higher imaging quality.





Durable and shockproof: The equipment is designed to be sturdy, wear-resistant, impact resistant, with strong resistance to damage, anti-static interference, and long service life.





Simple secondary development: Provide SDK (Software Development Kit).





Voice control is convenient and intelligent: it supports buzzers and voice guidance, guiding users to press and operate with appropriate fingers.
