Rfid Module NFC Contactless Smart Card Reading and Writing Module

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Contactless Card Interaction: Supports reading and writing of 13.56MHz RFID/NFC smart cards (ISO 14443A protocol) for secure access control and data exchange.
  • Multi-Interface Compatibility: Equipped with versatile communication interfaces (USB, RS485, RS232, TTL, NFC) to integrate seamlessly into diverse systems, from portable devices to industrial setups.

Key features

  • 1. Advanced Material Technology for Durability

    • With a compact PCB constructed from FR-4 material*, you can ensure robust performance in harsh environments. Its dense component layout and precise soldering outperform bulkier, less durable modules in industrial or portable applications.

  • 2. Multi-Interface Flexibility for Seamless Connectivity

    • With support for RFID, TTL, RS485, RS232, USB, and NFC interfaces, you can integrate the module into diverse systems—~50% more adaptable than single-protocol readers*. This eliminates the need for additional converters in mixed-technology setups.

  • 3. High-Frequency Precision for Reliable Performance

    • With a 13.56MHz frequency and ISO 14443A compliance, you can achieve rapid, error-free card reading/writing—ideal for high-traffic access control scenarios. This ensures ~20% faster data transfer than non-ISO-standard modules*.

  • 4. Portable Design for On-the-Go Applications

    • With a pocket-sized form factor smaller than a 1 jiao coin*, you can deploy the module in wearable devices, IoT systems, or mobile solutions. This contrasts sharply with bulkier, fixed-installation alternatives.

  • 5. Certified Compliance for Global Compatibility

    • With ISO 14443A certification*, you can ensure seamless interoperability with global smart card standards. This avoids compatibility issues common in non-certified modules, simplifying deployment across regions.
