Dual EM & MIFARE RFID Cards (Multi-System Access Control Smart Cards)

Dual EM & MIFARE RFID cards are hybrid contactless smart cards designed to support both 125kHz EM and 13.56MHz MIFARE technologies in a single credential. These multi-system access cards are engineered for environments that require compatibility with different access control infrastructures, allowing organizations to streamline identity management without issuing multiple cards. They are widely used in corporate buildings, universities, government facilities, hospitals, and mixed-system security environments where both legacy and modern RFID systems operate side by side.

Product Features

Dual Frequency RFID Technology

Combines 125kHz EM low-frequency and 13.56MHz MIFARE high-frequency technologies in one card, enabling compatibility with multiple access control systems.

Multi-System Compatibility

Works with both EM-based proximity readers and MIFARE smart card readers, reducing the need for separate credentials in mixed infrastructure environments.

Secure Access Management

Supports secure identification for both systems, allowing centralized control of user access rights across different platforms.

Printable PVC Card Surface

Smooth white PVC surface suitable for high-quality printing of logos, employee details, photos, barcodes, and organization branding.

Durable and Long-Lasting Construction

Made from high-grade PVC material designed to resist bending, cracking, and daily wear in high-usage environments.

Contactless Dual Interface Operation

Provides fast, touch-free authentication on both low-frequency and high-frequency readers for improved convenience and efficiency.

Unique Identification System

Each card contains unique identifiers for both EM and MIFARE systems, ensuring accurate user tracking and secure authentication.

Ideal for Migration Environments

Perfect for organizations transitioning from EM systems to MIFARE-based infrastructure without immediate full system replacement.
