HID 2050HNNSN iClass KF 2K/2 SR Prog Proximity Card
Access control deployments require credential technology that balances security, compatibility, and programming flexibility. The HID iClass KF 2K/2 SR Prog card delivers a dual-frequency solution for facilities transitioning from legacy proximity systems to higher-security iClass infrastructure, allowing you to phase upgrades without replacing readers across entire sites simultaneously.
Key Features
- Dual-technology credential supporting both 125 kHz proximity and 13.56 MHz iClass contactless smart card protocols
- 2K bit (256 byte) memory configuration with two application areas for storing multiple credentials or data sets
- Standard credit card form factor (CR80) for compatibility with existing badge programs and printing systems
- Short-range read distance optimized for controlled access points and secure entry applications
- Programmable format allows custom facility codes and credential numbering schemes during encoding
- iClass encryption and mutual authentication protects against credential cloning and replay attacks
- ISO-compliant construction ensures durability through typical badge lifecycle of 3-5 years
- Compatible with HID multiCLASS readers and legacy proximity readers during migration periods
The KF dual-frequency architecture solves a common integration challenge: upgrading security without the cost and disruption of wholesale reader replacement. Deploy these cards to users who access both legacy proximity doors and newer iClass-protected zones. The proximity side maintains backward compatibility with existing 125 kHz readers, while the iClass side enables you to add high-security applications—encrypted logical access, cashless vending, time and attendance—on the same credential. Programming flexibility means you can match existing facility code structures or implement entirely new numbering schemes as your system evolves.
The 2K/2 memory structure provides sufficient capacity for most multi-application deployments without the cost premium of higher-density cards. Two application areas allow logical separation—one for physical access, another for secondary functions like print release or building automation. Short-range read characteristics reduce the risk of unintended reads in high-traffic areas while maintaining the convenience of contactless presentation. For integrators managing phased upgrades or multi-site clients with mixed reader populations, this card delivers the credential interoperability that keeps projects on schedule and under budget.
