HID Signo 40 Contactless Smartcard Reader

The HID Signo 40 Contactless Smart Card Reader is a founding member of the HID Signo platform, offering a dynamic and adaptable solution for secure electronic access control. Designed for standard wall switch mounting, the Signo 40 supports an extensive range of credential technologies and form factors, including contactless smart cards, key fobs, and mobile devices. Its streamlined design and broad compatibility make it an ideal choice for commercial buildings, healthcare facilities, educational institutions, government sites, and enterprise environments.

Built to support today's evolving security needs, the HID Signo 40 features native Bluetooth® Low Energy and Near Field Communication (NFC) technology for HID Mobile Access, allowing users to securely unlock doors using their smartphones. The reader also supports Apple Enhanced Contactless Polling (ECP) for credentials stored in Apple Wallet. Certified secure element hardware safeguards cryptographic keys, while intelligent surface detection automatically recalibrates the reader to optimize read range and maintain reliable credential performance.

The HID Signo 40 is designed for simple ordering, installation, and long-term management. Native support for Open Supervised Device Protocol (OSDP) enables secure bidirectional communication between the reader and access control controller, while remote management capabilities allow administrators to configure, update, and maintain devices without requiring on-site service. The result is a scalable, future-ready access control solution that combines strong security with simplified deployment and maintenance.
