Bring more flexibility to access control at the door with a reader designed for mixed credential environments and phased system upgrades. The HID Signo40 supports both 13.56 MHz and 125 kHz technologies, allowing teams to accommodate current badge populations while planning a cleaner transition to newer credential formats. Its wall-mount design and pigtail connection simplify installation in standard access control deployments, while OSDP and Wiegand support make it easier to fit into both modern and legacy infrastructures. That matters when the goal is to improve security without forcing a full rip-and-replace. Mobile-ready capability adds another layer of credential options for organizations moving toward phone-based access. With a lifetime warranty and RoHS compliance, this reader is built for long service life in environments where uptime, compatibility, and controlled migration all matter. It is a strong fit for enterprises that want a reader platform with room to grow.
