Control entry with a reader designed for organizations that need flexibility at the door without adding complexity at the panel. HID Signo 40K combines multi-technology credential support, keypad input, and mobile-ready access in a wall-mount format suited to enterprise deployments. With support for 13.56 MHz and 125 kHz credentials, this model helps bridge legacy badge populations and newer smart credential programs. OSDP and Wiegand compatibility gives security teams options during upgrades, while the pigtail connection supports practical installation in a range of environments. The keypad adds a second factor at the reader for sites that require PIN-based verification or controlled fallback access. For facilities standardizing on HID Signo readers, the 40K model fits where a wall-mounted reader with keypad is preferred for secure entry points, shared spaces, or areas that need tighter access procedures. It is a strong fit for teams replacing older readers while preserving existing infrastructure investments.
