Product Overview

The DO-MU145 dual frequency RFID reader module is a compact, passive-range reader module engineered for access control, entry systems, and terminal equipment integration. Operating at both 125 kHz and 13.56 MHz, this module reads UID card numbers from EM4100, TK4100, MF S50, S70, NTAG203, and NTAG213 tags. It supports USB, TTL, RS232, and Wiegand 26/34 communication interfaces, making it a versatile choice for system integrators, access control manufacturers, and industrial project contractors who need reliable card reading across multiple protocols. The module is designed for surface-mount installation, enabling seamless embedding into advertising machines, LCD screens, electronic door locks, attendance terminals, and other space-constrained equipment.

As a leading do rfid reader manufacturer, we provide this module to distributors, OEM partners, and wholesale buyers who require stable production capacity, batch consistency, and long-term supply for large-scale deployment projects. Whether you are upgrading an existing access control system or building a new dual-frequency identification solution from scratch, the DO-MU145 delivers the compatibility and reliability that commercial and industrial applications demand.

Product Advantages

• Dual-frequency support: Covers both 125 kHz (EM4100/TK4100) and 13.56 MHz (ISO 14443A) tags in a single module, reducing SKU complexity for system integrators and distributors managing multi-site projects.
• Multiple interface options: USB, TTL, RS232, and Wiegand 26/34 are all supported, allowing the module to integrate directly into existing access control panels, turnstile controllers, and reader head assemblies without additional signal conversion hardware.
• Compact form factor: Measuring just 42 mm × 27 mm × 4 mm, the module fits into tight enclosures used in kiosks, vending machines, elevator panels, and medical device terminals, enabling OEM customers to add RFID functionality without redesigning their mechanical layouts.
• Wide power supply tolerance: Accepts 3.3 V to 5.5 V input, simplifying power design for projects that use standardized board-level voltages.

Technical Specifications

Industrial Applications

The DO-MU145 dual frequency RFID reader module is selected by system integrators, access control installers, and terminal equipment OEMs for projects where reliable card reading and multi-interface flexibility are critical. Common deployment scenarios include:

• Access control panels and door controllers: Integrates directly into entry system motherboards, providing dual-frequency support for both legacy 125 kHz proximity cards and newer 13.56 MHz smart cards during phased migration projects.
• Attendance and time-tracking terminals: Enables manufacturers of biometric and card-based time clocks to offer a single hardware platform that works across employee populations carrying different card technologies.
• Kiosks and self-service terminals: Used by public information kiosks, parking payment stations, and library checkout machines to identify users carrying contactless badges or membership cards.
• Electronic door locks and hotel lock systems: Provides a compact, low-power reader solution for battery-operated locks that need to read both legacy and modern credentials.
• Advertising machines and interactive displays: Enables touchless user authentication or personalization in digital signage applications where the reader must fit into a slim bezel.
• Medical device identification: Used in hospital equipment tracking and patient wristband readers where dual-frequency compatibility ensures interoperability across different card issuers.

For project contractors deploying 500+ reader points across multi-building campuses, the stable supply, batch consistency, and fast lead time from our factory reduce procurement risk and keep installation timelines on track.
