Product Overview
Narrow-Body Design and Integration
M21 is a narrow-body multi-function access terminal expressly developed for secure office environments where wall space is extremely limited, yet sophisticated and flexible verification remains a strict requirement. Engineered with an elongated vertical housing measuring 162 × 53 × 26 mm, it naturally conforms to slim door frames, side-wall mounting positions, and specific indoor architecture that favors a slender installation profile. This physical design minimizes spatial intrusion while maximizing utility. Despite its reduced structural width, the M21 consolidates face recognition, palm recognition, password verification, QR code authentication, and optional card reading capabilities—compatible with standard credentials and Rewriteable UID RFID Cards—into a single device. This comprehensive integration presents a highly practical option for modern, space-conscious access projects, ensuring that no biometric convenience is sacrificed for size.
Rapid Biometrics and Attendance Management
The hardware is reinforced with a vibrant 2.4-inch display, a tactile 16-button keypad, and a color plus infrared dual camera array supplemented by active infrared light. This robust combination achieves high-speed authentication in varying indoor lighting, executing face and palm verifications seamlessly in under 0.6 seconds. Such rapid processing ensures that personnel experience no delays during busy morning entries or shift changes. The terminal administers a substantial database comprising 1,000 users, 1,000 faces, 1,000 palms, and 1,000 passwords, all while maintaining a continuous log of up to 160,000 transactions. Outfitted to perform comprehensive human resources tasks, it incorporates built-in settings for 16 departments, 24 shifts, and 24 bells, transitioning effortlessly from a simple secure door controller to an intelligent attendance management node.
Advanced Security and Facility Ecosystem
Administrators are empowered to enforce rigorous access protocols using combined confirmation methods such as Password + Face and Password + Palm, pairing touchless entry with secure manual backups for sensitive areas. In comprehensive facility ecosystems—where IT teams might utilize RFID Blocking Bags for digital privacy, equipment managers track servers with a PCB On-Metal RFID Tag, and logistics handle staff uniforms using Silicone RFID Laundry Tags—the M21 seamlessly handles the critical task of human access control. A versatile multilingual design widens its appeal for international corporate rollouts, accommodating diverse workforce demographics. Connectivity functions include straightforward USB drive communication and clear voice prompts that guide users through the authentication steps. Operating dependably at DC 12V±5% within temperature ranges of 0°C to 45°C under non-condensing humidity, the device ensures long-term stability. Ultimately, M21’s slim silhouette solves difficult installation challenges where wide-body or traditional square terminals fail, delivering QR-enabled and multi-biometric security in an elegant, highly efficient vertical format.
