The HID 1431-34 Flexsmart cards combine HID proximity and Mifare smart card technologies in a single CR80 credential — the kind of dual-technology card that makes migration between access control systems considerably less painful. Encoded to N10002 34-bit format, they support mutual authentication and data encryption, giving you a solid foundation for high-security door access without committing to a single technology platform.

Each card is credit-card sized (86mm x 54mm) and sold in packs of 100. These are customised cards — encoded to your specified facility code and number range — so lead times run between 5 and 30 working days from order confirmation. Once your order is placed, the team will be in touch to confirm the exact format details before production begins.

Worth noting if you're planning a phased rollout or managing a mixed-reader environment: having both HID proximity and Mifare on the same card means one credential works across both legacy and newer infrastructure. Less reissuing, less disruption, and a cleaner transition on your timeline.
