HID 2051PNNMN iCLASS Keyfob 16K/2 Programmable
When you're deploying iCLASS access control across facilities with mixed security requirements, credential flexibility matters. The HID 2051PNNMN delivers 16K bits of memory across two programmable application areas, letting you encode multiple applications on a single credential—physical access plus cashless vending, time and attendance, or secure print release—without forcing users to carry multiple tokens.
Key Features
- 16K bit memory organized in two independent application areas for multi-function deployments
- iCLASS 13.56 MHz contactless smartcard technology with mutual authentication
- Durable keyfob form factor designed for high-cycle everyday use on keyrings
- Programmable configuration allows encoding custom facility codes and cardholder data
- Compatible with HID iCLASS readers across legacy and current product lines
- Read range up to 3.75 inches depending on reader configuration
- Operates across -35°C to 60°C temperature range for indoor and sheltered outdoor applications
The two-application architecture gives you deployment options that single-application credentials can't match. Partition one area for door access and reserve the second for ancillary systems—particularly useful in corporate campuses, healthcare facilities, and industrial sites where you're managing multiple credentialed systems but want to minimize the plastic in users' pockets. The keyfob format survives the wear patterns that cards don't—constant attachment to keys, exposure to pocket debris, repeated flexing—making it the right choice for maintenance teams, contractors, and other users who prioritize convenience over a formal badge presentation.
Programming requires HID-compatible encoders and follows standard iCLASS encoding protocols. The credential maintains full backward compatibility with existing iCLASS infrastructure while supporting migration paths to more secure encoding formats as your security posture evolves. For integrators managing multi-site deployments or phased rollouts, this credential provides the memory headroom and application flexibility to accommodate changing requirements without ripping out and replacing the entire credential population.
