Protect critical entry points with a reader designed for mixed credential environments and controlled migration paths. The HID Global SIGNO40 combines SEOS profile support with OSDP and Wiegand connectivity, giving security teams the flexibility to align with current controller standards while preserving room for future upgrades.
