• Can provide an open application program interface (SDK)
  • Fingerprint entry

Bio31M is an advanced embedded electro-silicon fingerprint module developed by ZKTeco specialized for the system integration device. It adapts ZKTeco ZKFinger V10.0 fingerprint algorithm as core, and adapts high-performance ARM core processor and internationally top semi-conductor fingerprint sensor. It is an off-line fingerprint module with ultra-high performance.
  • The algorithm supports automatic correction recognition, supports 360 ° rotation collection match 
  • Fingerprint entry, image capture, template extraction, fingerprint matching (including 1: 1 and 1: N), template deletion and other functions 
  • Light and small, can be flexibly embedded into a variety of products
  • Can provide an open application program interface (SDK)
