HID 2051HNNMN iCLASS Keyfob 16K/2 SR Prog
When you need to issue credentials for facilities with mixed access control and logical security requirements, standard proximity tokens leave you short. The HID 2051HNNMN iCLASS keyfob delivers 16K bits of memory across two application areas, giving you the capacity to store multiple credentials, biometric templates, or cashless vending data on a single token. The short-range 13.56 MHz contactless interface works with existing iCLASS readers while supporting migration paths to more secure encoding schemes.
Key Features
- 16K bit (2K byte) memory configuration with two independently programmable application areas
- 13.56 MHz contactless smart card technology with short-range read distance for controlled access scenarios
- iCLASS platform compatibility ensures drop-in integration with deployed HID infrastructure
- Programmable credential structure supports facility codes, cardholder data, and auxiliary applications
- Rugged keyfob form factor withstands daily pocket carry and keyring attachment
- Supports secure encoding with HID encoding services or on-site programming stations
- Multi-application capability allows physical access, PC logon, and cashless payment on single credential
- Field-programmable architecture enables credential updates without reissuing hardware
The dual-application memory architecture addresses deployments where you need to separate physical access credentials from secondary data. Encode one application area with standard access control credentials while reserving the second for biometric templates, time-and-attendance records, or print management data. This separation prevents credential conflicts in systems where different departments manage different applications. The 16K capacity provides enough overhead for future-proofing as system requirements expand.
The keyfob format suits environments where card carriers aren't practical—maintenance staff, healthcare workers in scrubs, or manufacturing personnel who need hands-free credential presentation. Program these fobs using HID's encoding software and compatible encoders, then manage them through your existing iCLASS access control platform. The short-range read characteristic reduces the risk of unintentional credential transmission in crowded areas while maintaining reliable performance at properly positioned readers.
