The HID® Signo™ 40 Keypad Reader combines PIN-based authentication with multi-technology card reading — covering 125kHz legacy credentials, 13.56MHz smart cards, and sub-2.4GHz technologies in a single unit. It's the kind of reader you specify when a card tap alone isn't sufficient: facilities handling sensitive data, restricted zones, or compliance-driven access policies where multi-factor authentication isn't optional.

Built for environments that aren't gentle on hardware, the capacitive touch keypad is engineered for harsh outdoor installation without sacrificing responsiveness. Cryptographic key storage is handled on-device, and optimised surface detection adds another layer of tamper resistance. If you're managing a mixed estate of legacy and modern credentials, the Signo 40 supports simplified migration — and full compatibility with HID Reader Manager means configuration and updates can be handled remotely across your deployment.

Connects via pigtail wiring and is also available in white. Manufacturer part number: 40KNKS-00-000000.
