HID® Signo™ Biometric Reader 25B

HID® Signo™ Biometric Reader 25B

'Designed For Real-World Performance'

The HID® Signo™ Biometric Reader is designed for "real-world" applications, where people have wet, dry, dirty or worn fingerprints. This is where the reader comes into a class of its own — capturing and reading fingerprints that other devices cannot.

Product Features & Benefits

Highly versatile

Unmatched flexibility to deploy multiple authentication modes, including biometric fingerprint and contactless physical and mobile credentials, with a single reader platform.

Unparalleled performance

Ultimate biometric fingerprint match reliability with patented multispectral imaging sensor that reads the subdermal layer of the skin for better accuracy.

Connected to the future

Easily configure and manage in the field with HID Biometric Manager or API integration, including support for software upgrades over the network.

With HID Global's patented multispectral imaging technology, the device captures fingerprint images from both the surface and the sub-surface, thereby delivering consistent read performance regardless of environmental and skin conditions. Industry-leading liveness detection capabilities also prevent spoof attempts leveraging fake fingers or latent fingerprints.

Safeguard against costly vulnerabilities with end-to-end security for each user’s biometric data. Biometric images are converted into a "template" (a string of data), meaning no image of the fingerprint is ever saved. Templates stored on the device or server are then also encrypted with AES-256.

The HID Signo Biometric Reader supports a variety of popular contactless credential technologies including Seos®, iCLASS SE®, iCLASS®, MIFARE DESFire, MIFARE Classic and HID Mobile Access® virtual credentials. Each device supports Near Field Communication (NFC) and Bluetooth out of the box.

This device is paired with the web-based HID Biometric Manager software that performs configuration and management of the reader, including firmware updates over the network. In addition, the software enables enrolment of user's fingerprint credentials for use with the different biometric authentication modes 1:1 verification and 1:N identification.

Door Controller Capabilities

Save on installation costs with built-in door access controller functionality. This enables the deployment of an intelligent and powerful edge based biometric solution that supports local access authorization and door control functions. The device is also capable of supporting a downstream reader for secure egress via OSDP connection.
