13.56MHz/125kHz Dual Frequency Contactless IC Card – 8K Bit & 64 Bit, PVC Material

Product Overview

The Dual-Frequency RFID Card combines 13.56 MHz IC technology with a 125 kHz ID chip in a single card, offering compatibility with different types of identification and access control systems. Designed for applications such as building access, parking management, hotel room entry, membership programs, and attendance tracking, it provides a convenient option for environments that use both high- and low-frequency RFID technologies.

Manufactured from new PVC with a thickness of 0.84 mm, the card is designed for everyday use and supports customized printing and encoding options for business and institutional requirements.

Dual-Frequency Compatibility

The card integrates two chip technologies to support different system configurations.

13.56 MHz IC Chip

• Memory capacity: 8 KB

• Memory structure: 16 sectors, with two passwords per sector

• Communication speed: 106 kbps

• Communication standard: ISO/IEC 14443 Type A

• Security: Independent 32-bit passwords for each sector and an anti-collision mechanism

The IC chip supports applications that require data storage and controlled access to card information. Its memory structure and security features can be used in compatible identification and access management systems.

125 kHz ID Chip

• Data format: 64-bit read-only identification

• Encoding: Fixed, factory-programmed ID

• Compatibility: EM4100-compatible systems

The ID chip provides a fixed identification number that cannot be rewritten through normal user operations. It is suitable for compatible systems that identify users or credentials by a preset card number.

System compatibility depends on the specific chip implementation, reader hardware, and access control software.

Physical Specifications

Reading distances can vary according to the reader, antenna design, installation environment, and operating conditions. Confirm the specified temperature range and durability requirements for the intended application before deployment.

Performance and Data Reliability

Repeated Read and Write Operations

The IC chip is specified for more than 100,000 erase/write cycles. This supports applications involving repeated data updates, subject to the chip's operating conditions and memory configuration.

Data Retention

The stated data retention period is up to 10 years. Actual retention depends on the chip specification, storage conditions, usage patterns, and environmental exposure.

Communication Compatibility

The 13.56 MHz IC component uses an ISO/IEC 14443 Type A communication interface, while the 125 kHz ID component is compatible with EM4100-based systems. These features allow the card to serve different identification requirements within a compatible infrastructure.

Security and Identification Features

The dual-chip configuration combines data access controls with fixed identification functionality.

• IC Data Protection: Two independent 32-bit passwords are specified for each sector, helping control access to protected memory areas.

• Anti-Collision Support: The IC chip's anti-collision mechanism helps compatible readers handle multiple cards within the same reading field.

• Fixed ID Number: The 125 kHz ID chip contains a factory-programmed identification number that is not designed for rewriting.

These features support credential management in compatible systems. The overall security of an access control solution also depends on reader configuration, credential management, encryption, and the system's authentication design.

Packaging and Customization

The cards are supplied in bags containing 10 pieces, with anti-static and dust-protection packaging specified.

Customization services may include:

• Company logo printing

• Card surface customization

• Chip encoding, where supported by the selected chip

• Bulk order supply

The manufacturer also reports more than 10 years of experience in chip production. Buyers can discuss the required chip configuration, printing artwork, encoding format, packaging quantity, and order volume before production.

Application Scenarios

The Dual-Frequency RFID Card can be used in a range of identification and access management applications, provided the card is compatible with the installed readers and software.

• Access Control: Credential identification for offices, residential buildings, and other controlled entrances.

• Parking Systems: Vehicle-related access identification in compatible parking facilities.

• Membership Cards: Member identification and access management for clubs, organizations, and service providers.

• Hotel Room Keys: Room access in systems designed to support the selected chip technology.

• Amusement Parks: Visitor identification and access management.

• Payment and Attendance Systems: Credential identification for compatible attendance or payment-related infrastructure.

Payment applications require appropriate system integration and security controls; the card itself does not guarantee payment functionality.

A Flexible RFID Solution for Multiple Systems

By combining 13.56 MHz IC and 125 kHz ID technologies, this dual-frequency card offers a practical credential option for organizations operating different RFID-based systems. Its PVC construction, specified memory and identification features, and available customization services support a range of access and identification projects.

Before ordering, confirm the exact chip models, memory configuration, reader compatibility, encoding requirements, and intended application with the supplier to ensure the card meets the project's technical requirements.
