Description
Product Overview
The Dahua DF-EV3C is a commercial-grade MIFARE DESFire contactless smart card engineered to deliver enterprise-level security for modern physical access control systems. Designed to resist unauthorized card cloning and credential skimming, this credential functions on standard high-frequency reader networks. It provides system installers and corporate security managers with a durable, long-lasting solution suitable for corporate campuses, government buildings, and multi-tenant facilities that enforce stringent identity management standards.
Key Technical Features
-
Advanced Bi-Directional Cryptography & Authentication: To safeguard corporate facility boundaries, the smart card incorporates robust multi-layered data security. It leverages contactless RF channel data encryption paired with 4-byte MAC (Message Authentication Code) verification to block credential tampering and man-in-the-middle attacks. Furthermore, the architecture supports application-level password authentication, allowing system integrators to segment permissions on a single credential across varied services such as door access, asset tracking, and cashless vending.
-
Installer-Grade Longevity & Tracking: Built for repetitive usage in demanding environments, the card structure is rated to survive a minimum of 100,000 Program/Erase (P/E) memory cycles and guarantees data retention over a span of up to 10 years. Each individual card carries a factory-programmed, non-alterable unique 7-byte serial number, simplifying backend database entry, automated hardware onboarding, and asset accountability logging for system installers.
