ZKTeco (ZK F21-ID with ADMS) Fingerprint A&C Device

The ZKTeco F21-ID with ADMS is an advanced, enterprise-grade biometric fingerprint time attendance and access control device engineered to deliver rapid authentication and secure door management. As a high-performance terminal, the F21 features ZKTeco’s cutting-edge SilkID fingerprint sensor. This specialized live-tissue scanner offers exceptional precision, minimizing false rejections by reading dry, wet, rough, or damaged fingerprints effortlessly. Equipped with a built-in ID card module, it supports dual-factor authentication via fingerprints, RFID badges, and PIN codes. This specific variant comes pre-activated with ADMS (Automatic Data Master Server) firmware, allowing the device to automatically push real-time attendance logs over WAN/Internet connections to a centralized cloud server. This feature eliminates the need for manual network polling, making it an excellent choice for multi-location retail chains, corporate branches, and high-traffic construction sites.

Key Features

• Advanced SilkID Fingerprint Sensor: Utilizes 3D live-tissue sensing technology to accurately verify challenging skin types (dry, wet, or rough) while providing robust anti-spoofing protection against fake or duplicated fingerprints.

• Pre-Activated ADMS Cloud Firmware: Features native Automatic Data Master Server protocols that push real-time biometric and transactional logs directly to centralized cloud management platforms over internet networks.

• Multi-Factor Authentication Suite: Supports multiple secure verification options, including Fingerprints, Proximity ID Cards, and alphanumeric PIN codes, allowing administrators to enforce dual-factor rules.

• Large Log and Credential Capacity: Accommodates a large internal database that stores up to 3,000 distinct fingerprint templates, 5,000 ID cards, and up to 100,000 historical transaction logs in non-volatile flash memory.

• Full Access Control Interfaces: Outfitted with standard hardware relays to control third-party electronic door locks, door exit buttons, status door sensors, external alarms, and doorbells.

• Flexible Network & Wiegand I/O: Equipped with a standard TCP/IP Ethernet port and an RS485 bus interface alongside Wiegand Input and Output ports for seamless integration into existing third-party access control panels.

• Vivid 2.4-Inch TFT Color Screen: Built with an intuitive graphical user interface (GUI) and a high-brightness color display that guides users through successful enrollment, clock-ins, and menu navigation.

• Built-In Auxiliary Input Interlock: Features a dedicated auxiliary input port that connects cleanly to fire alarms or smoke detectors, automatically unlocking doors during building emergencies.

• Anti-Passback & Advanced Security: Supports high-tier physical security logic including global anti-passback rules, multi-user verification groups, and custom time zones for restricted area access.

• Sleek, Durable Keypad Design: Designed with a compact, ultra-modern layout and a hard-wearing physical numeric keypad tailored for heavy, high-frequency everyday corporate and industrial environments.
