HID® Signo™ Biometric Reader 25B

Signo-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.

Advanced Biometric Security for High-Assurance Facilities

The HID Signo Biometric Reader 25B delivers enterprise-grade identity verification for environments where security cannot be compromised. Data centres, pharmaceutical facilities, research laboratories, and government buildings benefit from its patented multispectral imaging technology that reliably reads fingerprints regardless of skin condition—wet, dry, dirty, or worn.

The device's built-in liveness detection prevents spoof attempts using fake fingers or latent prints, making it ideal for facilities requiring the highest levels of access control assurance.

Beyond high-security environments, the Signo 25B excels in industrial settings where workers may have challenging fingerprint conditions. Manufacturing plants, construction sites, and healthcare facilities benefit from consistent biometric authentication without the frustration of repeated read failures.

The integrated door controller functionality reduces installation complexity, while support for multiple credential technologies including mobile access ensures seamless integration with existing access control infrastructure.

Frequently Asked Questions

How does multispectral imaging improve fingerprint reading?

Multispectral imaging captures fingerprint data from both surface and subsurface skin layers, enabling reliable reads even when fingers are wet, dry, dirty, or worn—conditions that cause traditional optical sensors to fail.

Can the Signo 25B operate as a standalone door controller?

Yes, the reader includes built-in door controller functionality supporting local access authorization and door control. It can also connect to a downstream reader via OSDP for secure egress.

What credential technologies are supported?

The device supports Seos, iCLASS SE, iCLASS, MIFARE DESFire, MIFARE Classic, HID Mobile Access, NFC, and Bluetooth credentials, providing comprehensive compatibility with existing access control systems.

How is biometric data protected?

Fingerprint images are converted to encrypted templates (never stored as images) using AES-256 encryption. The device features EAL 4+ rated crypto processor hardware for maximum security.

What is the user capacity for biometric identification?

The reader supports up to 5,000 users for 1:N identification (fingerprint search), 250,000 cardholders, and stores up to 1,000,000 transaction event logs.
