HID 2120BGGMVN iClass Prox Card Polyester/PVC 2K Bits (256 Bytes) with 2 Application Area Programming 125kHz
When you need to migrate from legacy proximity systems to iClass without replacing every reader, dual-technology credentials bridge the gap. The HID 2120BGGMVN combines 125kHz prox compatibility with iClass 13.56MHz smart card technology in a single credential, letting you phase infrastructure upgrades across multiple sites or buildings while maintaining consistent access control for all cardholders throughout the transition.
Key Features
- Dual-technology design supports both 125kHz proximity and 13.56MHz iClass读写 in one card
- 2K-bit (256-byte) memory configuration provides secure credential storage with room for multiple applications
- Two programmable application areas enable segmented access rights or integration with secondary systems
- Composite polyester/PVC construction delivers durability for high-cycle daily use environments
- Standard CR80 credit card form factor fits existing badge holders and lanyards
- HID iClass security features including mutual authentication and encrypted data transmission
- Compatible with existing HID prox readers during migration, readable by iClass readers post-upgrade
- Field-programmable to match site-specific facility codes and formats
This credential solves the common problem of needing to upgrade access control security without the operational disruption of replacing all credentials and readers simultaneously. Deploy iClass readers at high-security areas first while the prox side keeps working at secondary doors. As you replace legacy readers building-by-building, the same cards continue functioning without reissuance. The two application areas let you separate physical access from logical access, or partition credentials between building access and amenity systems like parking or print release.
The 256-byte memory capacity handles standard access control applications while maintaining the encrypted mutual authentication that distinguishes iClass from older prox technology. For integrators managing phased technology refreshes across campuses or multi-tenant facilities, this dual-credential approach eliminates the hard cutover that creates support nightmares and user confusion during transitions.
