The HID® 40430041B Crescendo™ 4000 Smart Card is a high-security, dual interface credential designed to support both physical access control and logical access authentication in a single card. Built for enterprise and government environments, this credential enables passwordless access, multi-factor authentication (MFA), and secure identity verification.

The Crescendo 4000 platform allows organizations to use one badge for building access, workstation login, VPN access, and secure applications, reducing the need for multiple credentials while improving overall security posture.

This specific configuration includes CUID matching, MIFARE DESFire® EV3 matching, and Prox matching, making it ideal for organizations migrating from legacy prox systems to more secure smart card environments.
