ZK Technology’s biometric terminals, designed to facilitate the collection of time records pertaining to employees’ activities, do not capture and store actual face images. Instead, our face recognition readers collect only sample data, convert it into binary data using mathematical algorithms and then store only a digital representation of the face (not an actual photograph), from which it is virtually impossible to recreate the original image.

Significant differences between AFIS devices and ZK devices

Image vs. Minutia Analysis

Image Vs Minutia

ZK Technology is committed to providing the most secure biometric solutions possible and constantly searches for the latest advances in sensor technologies and software approaches to incorporate into its products.

No face images are saved!

Face images are converted to mathematical representations BEFORE storing.

ZK Biometrics: Accuracy and Integrity

ZK biometric terminals are extremely accurate and virtually impossible to deceive, thanks to the integrated security components within are various sensors and firmware. These technologies combine to form the most powerful facial security solution in the industry.

For maximum accuracy, the terminals have a dynamic optimization process, enabling high face image resolution and quality with low false acceptance rates.

Incompatible with AFIS technology

Because of the different resolution, face size, and image enhancement processes of the two technologies, the data collected by a ZK terminals is virtually unusable by AFIS.
