The HID HID-900-PTNN is a compact, wired proximity card reader engineered for access control deployments where physical space constraints or aesthetic requirements eliminate traditional reader options. Built on HID's MultiCLASS SE platform, this mini mullion reader delivers enterprise-grade multi-technology credential support in a form factor measuring just 1.9" × 4.1" × 0.9". The RP10 combines secure communications, intelligent power management, and open protocol support to enable flexible credential architectures without requiring standardization across your organization.
The HID-900-PTNN integrates with any OSDP-compatible access control system, controller, or management platform. Its support for multiple communication protocols (OSDP, Wiegand, Clock & Data) ensures compatibility with legacy and modern systems. The reader's configurable mobile access capability enables progressive deployment strategies where smartphone-based credentials can be implemented without reader replacement. The mini mullion profile is particularly valuable in retrofit scenarios, corporate offices, educational institutions, and healthcare facilities where traditional reader footprints are impractical due to door geometry, mullion width, or aesthetic constraints.

The HID-900-PTNN represents a pragmatic solution to a recurring deployment constraint: multi-technology access control readers in space-limited installations. In retrofit and new construction scenarios alike, door mullion geometry and aesthetic requirements often conflict with reader placement. This mini mullion form factor eliminates that barrier without sacrificing credential flexibility or security posture.

Deployment Considerations:
For organizations managing mixed credential environments or planning incremental technology transitions, the HID-900-PTNN delivers flexibility without compromise. The compact footprint solves a genuine installation constraint, and the power efficiency delivers measurable operational cost reduction in medium to large deployments.
