Schlage 8440 MIFARE DESFire EV1 4K byte/32k bit ISO Clamshell Card

The Schlage 8440 MIFARE DESFire EV1 4K ISO Clamshell Card is a high-security smart credential designed for modern physical access control systems requiring advanced encryption and multi-application capability. Based on MIFARE DESFire EV1 technology, this credential operates at 13.56 MHz and supports secure, standards-based contactless communication with mutual authentication and strong cryptographic protection.

With 4K bytes (32K bits) of memory, these credentials can support multiple applications on a single card, such as access control, time and attendance, cashless vending, visitor management, and secure identity verification. This makes them ideal for enterprise environments transitioning to secure smart card infrastructures.

The rugged ISO clamshell construction provides exceptional durability, making it well suited for high-traffic environments where cards are frequently handled. Its reinforced design ensures long-lasting performance in commercial facilities, healthcare campuses, educational institutions, government buildings, and industrial environments.

The Schlage 8440 is commonly used in advanced access control deployments where enhanced security, encryption, and scalability are required beyond traditional proximity technology.
