I Introduction
1.1 characteristics
ZFM-70 series are separate fingerprint identification modules proposed by Hangzhou Zhian Technologies
Co., Ltd., which takes Synochip DSP as the main processor and optical sensor with Zhian’s own intellectual
property rights. The module performs series of functions like fingerprint enrollment, image processing, fingerprint
matching, serching and template storage
。
Compared to similar fingerprint products, the ZFM-70 module has the
following characteristics:
Touch sensing intelligent, more convenient operation
Acquisition window finger touch induction, works with low power consumption, more convenient. The
ZFM-708 module with the function, the module of ZFM-706 do not have this feature.
Independent intellectual property rights, image caputered clearly
Hardware module of optical fingerprint sensor, all technologies, from Hangzhou zhian independent
development, access to a number of national patents, optical path design is excellent, can gather to the clear
fingerprint image.
Finger match in range of
±
45°
When Fingerprint matching, support in range of
±
45
°
.
Responsive, strong adaptability of fingerprints
Fingerprint image reading, has sensitive response and judgment of the dry and wet fingers, to obtain the
optimal imaging quality, wide application of the crowd. Can also be self learning and adaptive function
customization, adjust the parameters automatically according to the change of the habits of the users, such as
climate, to better match.
A particular highlight light green LED, anti-aging excellent performance
Using a specific green bright light source component, ultra low attenuation, longer service life, better
performance and more durable.
Easy to develop
Without the need for fingerprint recognition of professional knowledge can be applied, the ZFM-70 module
provides rich control instruction, can develop powerful application of fingerprint identification system
。
Flexible to set security level
For different application occasions or environment, users can set different security level 1 to level 5
