JP-7941M 13.56MHz HF RFID Card Reader Module 5V Wiegand UART Interface Industrial Grade for Access Control System

JP-7941M Card Reader Module

Product Overview

The JP-7941M Card Reader Module is a compact, industrial-grade 13.56MHz RFID reader module supporting ISO/IEC 14443 Type-A standard cards, including S50, S70, and FM1208 compatible cards. Designed for reliable UID reading in access control, time attendance, and identity verification applications, this module delivers a read range of over 5cm with low power consumption of just 40mA at DC 5V. Housed in a space-saving 36mm × 17.8mm × 7mm form factor (antenna excluded), the JP-7941M supports both Wiegand (with TTL customization available) and UART interfaces, enabling seamless integration with legacy access control panels and modern embedded systems. With industrial-grade reliability and a 0°C to 60°C operating range, the JP-7941M is the ideal choice for OEMs and system integrators requiring a cost-effective, high-performance 13.56MHz reader module for indoor installations.

Key Advantages

• Over 5cm Read Range: Achieves reliable reading distance exceeding 5cm — outperforming many compact readers in its class, providing more user-friendly operation without precise card placement.

• Ultra-Low Power Consumption: Draws just 40mA typical current — ideal for power-sensitive deployments, battery-backed systems, and large-scale installations where multiple readers share a limited power supply.

• Compact Industrial Design: Measures only 36mm × 17.8mm × 7mm — fits easily into slim readers, keypads, and space-constrained access control terminals.

• Flexible Interface Options: Supports Wiegand (with TTL customization) and UART interfaces — enabling direct connection to legacy Wiegand-based controllers, embedded systems, and modern access control panels.

• Card Compatibility: Supports S50, S70, and FM1208 compatible cards — covering a broad range of 13.56MHz ISO14443 Type-A cards.

• Industrial-Grade Reliability: Rated for 0°C to 60°C operation with robust performance in demanding indoor environments — suitable for office buildings, retail spaces, and controlled-access facilities.

Why Choose This Module?

• Compact Footprint for Integrated Designs: At just 36mm × 17.8mm × 7mm, the JP-7941M fits into the most space-constrained enclosures — slim readers, keypad terminals, and compact access control devices. This enables industrial designers to create modern, slim-profile products without sacrificing read performance or interface flexibility.

• Versatile Integration Across Platforms: The combination of Wiegand (the industry standard for access control panels for over 30 years) and UART interfaces provides universal compatibility. Existing Wiegand-based controllers connect directly — no protocol conversion, no additional hardware. For embedded designs, UART offers simpler microcontroller integration. The TTL-customizable Wiegand option provides additional flexibility for OEMs with specific voltage or interface requirements.

• Extended Read Range for Better User Experience: With >5cm read range, the JP-7941M provides forgiving positioning — users don't need to precisely align their cards, reducing failed attempts and speeding up entry at busy access points.

• Cost-Effective 13.56MHz Solution: Provides reliable ISO14443 Type-A reading at a competitive price point — making it the ideal choice for budget-conscious OEM projects requiring dependable contactless card reading.

• Proven Card Compatibility: Supports S50, S70, and FM1208 compatible cards — covering the most commonly deployed 13.56MHz ISO14443 Type-A cards in access control and time attendance systems worldwide.
