HID 2120BGGNVN Composite iClass Prox 2K/2 Credential
When your access control deployment spans multiple legacy Prox readers and newer iClass infrastructure, maintaining separate credential inventories creates administrative overhead and user friction. The HID 2120BGGNVN combines 125 kHz proximity and 13.56 MHz iClass technology in a single composite card, letting you migrate systems incrementally while maintaining one credential per cardholder across mixed reader environments.
Key Features
- Dual-technology design with both 125 kHz HID Prox and 13.56 MHz iClass credentials in one card
- Composite construction balances durability with cost-effectiveness for moderate-use environments
- 2K-bit memory configuration with two application areas for credential data and auxiliary functions
- Standard CR80 credit card form factor for compatibility with existing badge printers and holders
- Works with both proximity and iClass readers without requiring users to carry multiple cards
- Supports phased migration strategies from legacy Prox systems to secure iClass infrastructure
- Compatible with HID's extensive ecosystem of readers, controllers, and management platforms
This credential architecture solves a common integration challenge: you've invested in proximity-based access control, but need to migrate to iClass for enhanced security or multi-application capability. Rather than forcing a forklift upgrade or managing two cards per user, the 2120BGGNVN bridges both technologies. Your cardholders present one credential to any reader in your facility—legacy Prox readers authenticate via the embedded 125 kHz chip, while upgraded iClass readers leverage the secure 13.56 MHz technology. This approach lets you replace readers building-by-building or door-by-door without re-carding your entire population.
The composite construction provides adequate durability for typical office and light industrial applications where cards remain in holders or wallets between uses. For deployments prioritizing maximum longevity in harsh environments or heavy-duty access patterns, consider upgrading to PVC or composite alternatives, but for most installations, this credential delivers reliable performance at a practical price point. The 2K/2 configuration provides sufficient memory for standard access control credentials plus room for secondary applications like cashless vending or print management integration.
