RFID IC Card/MF Card 13.56Mhz 125kHz Induction Card for Access Control


SKU: 000039 Category: Tags: , , , , , , , ,


The RFID IC Card, often referred to as an MF Card, is a contactless smart card that operates at two different radio frequencies: 13.56 MHz and 125 kHz. These cards are commonly used in access control systems and other applications for secure identification and authentication. Here’s a description of their key features and functions:

**1. RFID Technology:** The RFID (Radio-Frequency Identification) IC Card uses radio waves to communicate with RFID readers. It contains an embedded microchip and an antenna, allowing it to transmit and receive data wirelessly.

**2. Dual-Frequency:** These cards are dual-frequency, operating at both 13.56 MHz and 125 kHz. The two frequencies cater to different types of RFID systems and applications.

**3. 13.56 MHz:** The 13.56 MHz frequency is commonly associated with high-frequency (HF) RFID technology. It is used for more advanced and secure applications, such as contactless payment cards and access control systems.

**4. 125 kHz:** The 125 kHz frequency is part of the low-frequency (LF) RFID technology. It is often used for proximity card systems and access control applications.

**5. Access Control:** These cards are frequently used for access control and security systems. Users can gain access to secure areas by presenting their RFID cards to card readers.

**6. Identification:** Each RFID card has a unique identifier stored on its microchip. When presented to a card reader, this identifier is transmitted and used to verify the user’s identity.

**7. Contactless:** RFID cards do not need to make physical contact with the card reader. Users can simply wave or tap the card near the reader for quick access.

**8. Secure Authentication:** These cards provide a higher level of security compared to traditional key-based access systems. The unique identifiers and encryption methods make it difficult for unauthorized users to replicate or access the card’s data.

**9. Customization:** RFID IC Cards can often be customized with user-specific information, such as names, photos, or other data.

**10. Versatile Applications:** In addition to access control, RFID IC Cards are used in applications like public transportation, payment systems, library management, and inventory tracking.

**11. RFID Readers:** To use these cards, you need RFID card readers that operate at the appropriate frequencies (13.56 MHz and 125 kHz).

**12. Wristbands and Key Fobs:** RFID technology is not limited to cards; it is also available in wristbands and key fobs for convenience and versatility.

RFID IC Cards operating at 13.56 MHz and 125 kHz are valuable tools for secure access control and user authentication in various environments. They are widely adopted in commercial and institutional settings to enhance security and streamline access procedures.
