The HID DuoProx II 1336LGGMN cards are a trusted choice for organizations that need the convenience of dual-technology credentials in one dependable card. Designed to combine 125 kHz HID proximity with a magnetic stripe, the DuoProx II is ideal for facilities that still rely on both access control and legacy card-based systems. HID describes the 1336 as a card that combines proximity, magnetic stripe, and photo identification capability in a standard card body with a graphics-quality surface for badge printing.

Built to standard card dimensions and optimized for everyday badge use, the 1336LGGMN is well suited for corporate offices, healthcare facilities, schools, government buildings, and other secure environments that require consistent credential performance. HID’s official product information notes that the card supports photo ID printing, standard credit-card size and thickness, slot punch capability, and a lifetime warranty, making it a reliable option for long-term deployment.

For buyers needing the common 26-bit H10301 format, these DuoProx II cards remain a practical solution for system compatibility and straightforward enrollment. The 26-bit H10301 format uses a facility code and card number structure commonly found in installed access systems, and this exact 1336LGGMN configuration is widely sold for that purpose.
