HID 2120BGGMVR Composite iClass Prox 2K/2 Credential
When your access control deployment spans legacy 125 kHz prox readers and newer 13.56 MHz iClass systems, managing two separate credential formats creates administrative overhead and user friction. The HID 2120BGGMVR combines both technologies in a single composite card, letting you migrate systems at your own pace while maintaining one credential per cardholder across mixed reader infrastructures.
Key Features
- Dual-technology credential: 125 kHz HID Prox and 13.56 MHz iClass in one card
- 2K bit (256 byte) memory configuration with two application areas
- Composite construction balances durability with cost-effectiveness for standard use environments
- Compatible with existing HID Prox and iClass SE/SR reader infrastructure
- Standard CR80 credit card dimensions (2.125" x 3.375") for universal acceptance
- Supports secure identity data (SIO) encoding on iClass portion
- Graphically printable surface for photo ID badging integration
- 26-bit through custom format support on prox side
This dual-technology approach solves a common migration challenge: you've invested in prox readers across facilities but need to deploy iClass for higher-security zones or new construction. Rather than replacing all readers simultaneously or issuing multiple cards per person, the 2120BGGMVR provides backward compatibility with prox while enabling forward movement toward encrypted credential technology. The iClass portion supports mutual authentication and encrypted data transmission where reader infrastructure permits, while the prox chip handles legacy doors during transition periods.
The composite card body offers adequate durability for typical office and light industrial environments where cards live primarily in badge holders or wallets. The 2K/2 memory structure provides sufficient capacity for standard access control applications plus secondary uses like cashless vending or print release through the two separate application areas. For integrators managing phased system upgrades or multi-site clients with varied reader populations, this credential format reduces enrollment complexity and helps justify iClass reader deployment by eliminating the immediate need to replace entire systems.
