JP-M9-WD-UH-00 Card Reader Module

 

Product Overview

     The JP-M9-WD-UH-00 Card Reader Module is a high-performance 13.56MHz RFID reader module supporting ISO14443A protocol cards (S50, S70, Fudan F08, UltraLight, etc.) and ISO14443B cards, including second-generation ID cards. This module provides active card reading capabilities — automatically detecting and reading both the physical card number and up to 48 bytes of valid data. It supports configurable data format and data length, with the ability to read encrypted cards, making it suitable for access control, time attendance, identity verification, and payment applications. Offering four communication interface options — USB, UART TTL, RS232, and RS485 — the JP-M9-WD-UH-00 provides flexible integration with PC-based systems, embedded controllers, and industrial networks. Housed in a 72mm × 45mm module with an integrated detachable antenna, it operates from 3.3V to 5V with typical current consumption of 60mA, card read times under 100ms, and extended read distances of 5–8cm. Compatible with Windows, Linux, and Android operating systems, the JP-M9-WD-UH-00 is the ideal choice for OEMs and system integrators building access control terminals, time attendance devices, identity verification kiosks, and industrial automation systems requiring enhanced read range and versatile connectivity.

Key Advantages

• ISO14443B Support: Reads ISO14443B cards including second-generation ID cards — enabling government, financial, and enterprise identity verification applications where national ID reading is required, a capability not offered by many standard 13.56MHz reader modules.

• Extended Read Distance: Delivers 5–8cm read range — significantly longer than standard 3–5cm readers, providing forgiving card placement and faster user throughput at access points.

• Active Card Reading with Data Capture: Automatically detects and reads cards, capturing both the physical card number and up to 48 bytes of valid data — enabling application-specific data storage and retrieval without host intervention.

• Configurable Data Format and Encrypted Card Support: Supports flexible configuration of data format and data length, with the ability to read encrypted cards — adapting to different application requirements and providing enhanced security for sensitive applications.

• Four Interface Options: Supports USB, UART TTL, RS232, and RS485 — providing universal connectivity for PC-based systems, embedded controllers, and industrial networks.

• Flexible Antenna Design: Integrated by default with detachable antenna option — allowing designers to position the antenna for optimal read performance in various form factors while maintaining the module's compact footprint.

• Fast Card Reading: Delivers under 100ms read time — enabling quick, responsive user experiences in high-throughput environments.

• Status Indicators with Controllable Buzzer: Built-in blue LED indicator with controllable buzzer — providing immediate visual and audible feedback for card detection, read status, and system alerts.

Why Choose This Module?

• ISO14443B Support — Government and Enterprise Ready: While many 13.56MHz readers only support ISO14443A (S50, S70, UltraLight), the JP-M9-WD-UH-00 also supports ISO14443B — enabling reading of second-generation ID cards. This is a critical requirement for government identity verification, financial applications, and enterprise systems where national ID cards are used. One module covers both standard access control cards and government-issued IDs.

• Extended Read Range for Better User Experience: With 5–8cm read range, the JP-M9-WD-UH-00 provides significantly more forgiving positioning than standard 3–5cm readers. Users don't need to precisely align their cards — simply tap or wave, reducing failed attempts and speeding up entry at busy access points. This extended range is particularly valuable in high-traffic environments where speed matters.

• Four Interfaces for Industrial and Enterprise Integration: The combination of USB, UART TTL, RS232, and RS485 provides universal connectivity across diverse platforms — PC-based systems, embedded controllers, industrial networks, and legacy access control panels. RS485 support enables long-distance communication (up to 1200 meters) in industrial environments, while RS232 provides compatibility with legacy serial systems. This interface flexibility reduces inventory complexity and enables component standardization across product lines.

• Flexible Antenna Design for Various Form Factors: The integrated detachable antenna allows designers to either use the default integrated antenna for compact designs or detach it and position the antenna separately for optimized read performance in larger enclosures or metal environments. This flexibility enables one module to serve multiple product variations — from slim readers to industrial terminals — without hardware redesign.

• Active Card Reading and Data Capture for Standalone Operation: The JP-M9-WD-UH-00 automatically detects cards and reads both the physical card number and up to 48 bytes of valid data — eliminating the need for complex host-side card detection and data retrieval logic. This simplifies firmware development, reduces host CPU load, and enables standalone operation where the module handles card reading independently, making it ideal for embedded systems and battery-powered devices that cannot afford constant host polling.
