Description
PA22 – 3-in-1 Contactless Palm Recognition Device
Palm recognition device - PA22 is an advanced biometric recognition device developed by ZKTeco, utilizing modern Computer Vision technology. The product is designed to recognize three palm elements simultaneously: palm vein, palm print, and palm shape, providing superior security and a contactless, hygienic, convenient, and fast user experience.
The device is supported by the ARMATURA platform, optimized for high-end access control and biometric time attendance needs in modern agencies, businesses, and factories.
Contactless Palm Recognition Technology – 3 Layers of Biometric Authentication
PA22 uses the Armatura PALM 12.0 algorithm with multi-dimensional recognition technology, allowing for:
-
Simultaneous authentication by palm vein, print, and shape
-
No touch required, just place hand in front of the device
-
Fast recognition speed of only ≤ 0.4 seconds
-
Wide angle tolerance up to ±60°, stable operation at various hand placement angles
-
Flexible recognition distance from 18cm to 35cm
This helps limit physical contact, ensuring hygiene – ideal for medical, food, or strictly controlled environments.
Powerful Configuration – Stable Operation
The device is equipped with high-performance hardware:
-
Dual-core ARM 1.0GHz processor
-
256MB Flash + 256MB RAM
-
2.4-inch TFT color screen (320x240) displaying an intuitive, user-friendly interface
All integrated into a compact, durable device, easy to install in various locations.
Impressive Storage Capacity – Suitable for Businesses of All Sizes
Palm storage capacity: 1,000 templates (1:N)
-
RFID card capacity: 5,000 users
-
Transaction capacity: 50,000 records
PA22 can be used standalone or integrated into large-scale access control systems via specialized software such as ZKBioAccess IVS.
Diverse Communication – Easy System Integration
PA22 supports all modern communication standards:
-
TCP/IP
-
RS485
-
Wiegand
-
USB Host
-
Wi-Fi (optional)
This allows the device to easily connect to internal networks, control centers, auxiliary readers, or other peripheral devices.

Data Security – AES-128 Encryption Standard
Security is always a key factor in biometric systems. PA22 is equipped with:
-
AES-128 encryption
-
Live palm detection (anti-spoofing with images, models)
-
Magnetic tamper sensor – alerts when tampered with
Ensures absolute user data protection, preventing forgery or unauthorized access.
