HID 1336LGGMN DuoProx II Proximity Card
The HID 1336LGGMN is a factory-programmed DuoProx II proximity credential—a 125kHz access card with integrated magnetic stripe backup. It deploys into any HID proximity reader ecosystem and handles wallet carry without performance degradation, making it the standard choice for facilities rolling out credential refresh or multi-site badge programs where durability and read consistency matter more than density.
Overview
This card combines passive 125kHz proximity technology with magnetic stripe encoding on a single credential. The 1336LGGMN ships pre-programmed with sequential ID assignment—critical for rapid enrollment into larger badge populations. Passive design (no battery) means infinite operational life and no maintenance burden. The flexible, durable polycarbonate construction resists warping and cracking, unlike brittle legacy cards. Read range remains consistent even with keys and coins nearby, and performance is unaffected by body shielding or environmental temperature swing—a real factor in outdoor access points or warehouse loading docks.
Compatibility
The DuoProx II format is compatible with all HID proximity readers operating at 125kHz, including the HID ProxPro series, 5355 readers, and any third-party reader certified for HID Prox credentials. If your facility runs a mixed reader environment (some older, some newer HID hardware), verify the specific reader model supports the DuoProx II format—most modern HID deployments do, but legacy readers may require format conversion or reader upgrade. Magnetic stripe encoding allows secondary fallback authentication on dual-technology readers or legacy mag-stripe systems in transition scenarios.
Installation Notes
Cards arrive pre-programmed with sequential numbering. Cross-reference documentation correlating external card number to internal programmed ID is provided for rapid badge office enrollment. Minimum order quantity is 100 units—confirm your enrollment volume before purchase. Cards support formats up to 85 bits with over 137 billion unique code combinations, sufficient for large multi-building or enterprise deployments.
