HID 2120BGGMNM HID Composite iClass Prox 2K/2 Programmed Credential
When you're deploying a dual-technology access control system that needs to support legacy proximity readers while transitioning to secure iClass infrastructure, you need credentials that work across both technologies without forcing a forklift upgrade. The HID 2120BGGMNM delivers factory-programmed iClass 2K/2 and 125 kHz prox technology in a single composite card, letting you phase in newer readers while maintaining compatibility with existing Prox infrastructure.
Key Features
- Dual-technology credential supporting both iClass 2K/2 (13.56 MHz) and HID Prox (125 kHz) in one card
- Factory-programmed and ready to deploy out of the box
- Composite construction provides durability for daily use in commercial and enterprise environments
- Standard CR80 credit card form factor (3.375" x 2.125") fits existing badge holders and lanyards
- Compatible with HID iClass and legacy Prox readers for staged migration projects
- 2K bit memory on iClass side supports multiple applications beyond basic access control
- Enables backward compatibility during system upgrades without re-credentialing entire user base
Migration projects often stall because replacing every reader simultaneously isn't practical or budget-friendly. This dual-technology card solves that problem by presenting the appropriate credential technology to whatever reader it encounters. Deploy new iClass readers in high-security zones while legacy Prox readers continue operating in lower-risk areas. Users carry one credential that works everywhere, and you upgrade infrastructure on your timeline rather than being forced into a complete overnight changeover.
The composite construction balances cost and durability for environments where cards see regular use but don't require the extreme abuse resistance of clamshell housings. The factory programming eliminates the need for on-site encoding equipment during initial deployment, though the iClass side remains field-programmable for custom applications. Standard CR80 dimensions ensure compatibility with existing photo ID badging systems and visual security programs already in place.
