HID 2051PNNNN iClass Keyfob 16K/2 Programmable
When you need reliable credential management for multi-application access control deployments, iClass keyfobs deliver the flexibility to consolidate physical access, cashless vending, and time-and-attendance onto a single credential. The 2051PNNNN offers 16K bit memory with two programmable application areas, enabling you to migrate legacy systems or layer new applications without reissuing credentials across your installed base.
Key Features
- 16K bit (2K byte) memory structure provides capacity for multiple applications on one credential
- Two independently programmable application areas support phased migrations and multi-tenant deployments
- 13.56 MHz contactless smart card technology operates at standard HID iClass read ranges
- Rugged keyfob form factor withstands daily pocket/keychain carry in commercial environments
- Compatible with HID iClass readers and the broader iClass SE platform for future upgrades
- Supports secure authentication using HID's mutual authentication protocol
- Direct replacement for legacy proximity keyfobs when paired with iClass SE readers in migration mode
- Standard 26-bit or custom format encoding available for integration with existing access control panels
The two-application architecture is particularly valuable when you're running parallel access control systems during a facility consolidation, or when end users require both building access and secure print release on the same credential. Each application area operates independently—you can encode building access to one area and assign parking or elevator control to the second without cross-contamination or programming conflicts.
iClass credentials maintain backward-read compatibility with standard iClass infrastructure while supporting the security enhancements available in iClass SE deployments. This means you can deploy these keyfobs today in a standard iClass environment and activate advanced features like Secure Identity Object (SIO) or mobile integration later without replacing credentials. The keyfob format is ideal for facilities where card-based credentials aren't practical—manufacturing floors, healthcare environments, or any deployment where users need hands-free operation at readers. Standard HID ordering and encoding processes apply, with support for both factory programming and field encoding depending on your deployment workflow.
