HID 2051CNNNN iClass Keyfob 16K/2 Configured
When you're deploying access control systems that demand secure credential management without the bulk of proximity cards, the HID iClass keyfob delivers 13.56 MHz contactless technology in a form factor that end users actually carry. This configured credential arrives programmed and ready to provision into existing HID iClass readers, eliminating the programming overhead that slows down large-scale rollouts or retrofit projects where you're inheriting partial systems.
Key Features
- 13.56 MHz contactless smart card technology using HID's iClass platform for mutual authentication and encrypted data transfer
- 16K bit (2 application areas) memory configuration supporting multiple applications on a single credential
- Pre-configured format eliminates on-site encoding requirements and accelerates deployment timelines
- Compact keyfob form factor designed for daily carry on key rings or lanyards
- Compatible with standard HID iClass readers across multi-site installations
- Durable construction engineered for high-cycle use in commercial and industrial environments
- Read range performance suitable for hands-free access in parking or vehicle gate applications
- Supports secure identity data storage with encryption to meet compliance requirements
The iClass platform's two-application memory architecture gives you flexibility to segment physical access from other functions—logical access, cashless vending, time and attendance—on the same credential. This becomes critical in enterprise environments where IT security policies require separation between building entry and network authentication, or where you're managing contractor credentials that need time-limited parking access alongside permanent door permissions.
Because these keyfobs ship configured, you're not burning installation time encoding credentials at the job site or dealing with encoding hardware that may not be compatible with newer reader firmware. For retrofit scenarios where you're matching format to legacy systems, or phased migrations where you're gradually replacing proximity with iClass, the pre-configured approach eliminates a common failure point. The keyfob's compact footprint and attachment hole make it practical for environments where card-based credentials create pocket bulk or get forgotten—distribution centers, healthcare facilities, and manufacturing plants where workers prefer minimal carry.
