13.56MHz RFID Smart Card Reader Module RS232/TTL Interface

Product Overview

This 13.56MHz RFID smart card reader module is designed for system integrators, access control manufacturers, industrial automation engineers, and IoT solution providers who require reliable contactless card reading capabilities in commercial and industrial deployments. The module operates at 13.56MHz frequency and supports ISO/IEC 14443 TypeA protocol, making it compatible with a wide range of MIFARE and Ultralight cards commonly used in access control systems, payment terminals, attendance tracking, and identification kiosks.

Wholesale buyers and project contractors choose this reader module because it provides stable read performance across varying environmental conditions, supports multiple card types including MF S50, S70, Ultralight, and F08, and offers flexible TTL interface integration for embedding into larger systems. As a manufacturer with over two decades of production experience, DO RFID Reader ensures batch consistency and long-term supply reliability for large-scale deployments.

The module is specifically engineered for OEM customers who need a compact, low-power card reading solution that can be integrated into custom enclosures, kiosk terminals, time clocks, self-service machines, and embedded control panels. The dual-size PCB design with separate antenna board allows flexible placement within existing product housings.

Product Advantages

• Multi-card Compatibility – Supports MF S50, S70, Ultralight, F08, and other ISO/IEC 14443 TypeA compliant cards, reducing the need for multiple reader modules in a single system.
• Wide Voltage Range – Accepts 3.3V to 5.5V DC power input, simplifying power supply design across different host systems and eliminating the need for additional voltage regulation.
• Dual Interface Options – Available with RS232 or TTL interface to match existing system communication requirements without protocol conversion hardware.
• Adjustable Baud Rate – Supports 9600 to 115200 bps with default 9600 bps, allowing integration into both legacy and modern control systems.
• Separate Antenna Design – The 75mm x 55mm antenna board connects via J2 pins, enabling physical separation between the reader module and antenna for optimized placement inside equipment enclosures.
• Industrial Temperature Range – Operates reliably from 0°C to +95°C with storage capability from -20°C to +80°C, suitable for both indoor commercial environments and semi-outdoor industrial deployments.
