NexaKey SN-K3 Standalone RFID + PIN Access Controller
The NexaKey SN-K3 Standalone RFID + PIN Access Controller is a compact, all-in-one door access solution combining RFID card reading and PIN keypad entry in a single sleek unit — giving offices, homes, schools, and small commercial premises across Bangladesh a flexible, affordable way to control who enters a secured door without the cost or complexity of a networked access control system.
As a true standalone access controller, the SN-K3 requires no software, no PC connection, and no ongoing subscription — administrators programme users directly at the device using the integrated keypad. The system supports a generous 2,000-user card capacity alongside 15 sets of valid PINs, making it suitable for small offices, residential buildings, retail shops, and educational institutions where dozens of authorised users need reliable daily access.
The standout strength of the SN-K3 is its flexible authentication mode: administrators can configure the door to unlock via
RFID card only, PIN password only, or a combined card-plus-password mode for higher-security entry points. This dual-layer authentication option makes the SN-K3 suitable for both everyday convenience (single-tap card entry) and elevated security requirements (card + PIN combination) within the same hardware unit — without needing to purchase separate devices for different security tiers.
Built with a touch-sensitive acrylic panel keypad and clear LED status indicators, the SN-K3 offers smooth, durable daily operation even under high-frequency use. Its NO/NC relay output ensures straightforward compatibility with standard magnetic locks, electric strikes, and electromagnetic locks already deployed in most Bangladeshi commercial and residential access control installations — making it a simple drop-in replacement or new installation choice for security integrators.
Designed for professional home and office use, the SN-K3 also functions as an external card reader when paired with a separate access control panel, adding deployment flexibility for installers building tiered or multi-door security systems.
