JP-7903A1 Card Reader Module

Product Overview

The JP-7903A1 Card Reader Module is a high-performance dual-frequency RFID reader module supporting 13.56MHz (ISO14443 A/B/C, ISO15693, iClass, SONY) and 125kHz (EM4100 series) card standards in a single compact package. This module reads a comprehensive range of card types — including second-generation ID cards, ISO15693 cards, iClass cards, SONY cards, and EM4100 series cards — with read distances exceeding 8cm for ISO15693, iClass, and EM4100 cards, and over 3cm for second-generation ID cards. Featuring an integrated antenna, built-in buzzer, and dual-color LED indicator, the module provides immediate visual and audible feedback without external components. The JP-7903A1 offers three interface options (Wiegand with TTL customization, UART, and USB) and is housed in an ultra-compact 47mm × 26mm × 5mm form factor with industrial-grade -20°C to 70°C operation. With OEM customization support, this module is the ideal choice for system integrators building space-constrained access control terminals, identity verification kiosks, and multi-card environments requiring broad card compatibility.

Key Advantages

• Broadest Card Compatibility in Its Class: Supports ISO14443 A/B/C, ISO15693, iClass, SONY, and EM4100 series cards — covering virtually all major card standards used in access control, payment, and identification systems worldwide.

• Exceptional Read Range: Delivers >8cm for ISO15693, iClass, and EM4100 cards, and >3cm for second-generation ID cards — outperforming many compact readers and providing forgiving, user-friendly operation.

• Integrated Feedback Indicators: Built-in dual-color LED and buzzer provide immediate visual and audible feedback for card detection, read status, and system alerts — eliminating the need for external indicator components and simplifying PCB design.

• iClass Card Support: Reads HID iClass cards — enabling integration with existing iClass-based access control systems without requiring separate readers or hardware changes.

• Second-Generation ID Card Compatibility: Supports reading of second-generation ID cards (ISO14443 B) — making it suitable for government, financial, and enterprise identity verification applications.

• Three Interface Options with OEM Customization: Supports Wiegand (with TTL customization), UART, and USB interfaces — with full OEM customization support for interface, form factor, and feature adjustments.

• Ultra-Compact Integrated Antenna Design: Measures only 47mm × 26mm × 5mm with built-in antenna — the smallest form factor in the JP-7903 series, ideal for the tightest space-constrained devices while maintaining excellent read performance.

• Industrial-Grade Reliability: -20°C to 70°C operating range — suitable for outdoor access control, industrial environments, and extreme-climate deployments.

Why Choose This Module?

• The Most Comprehensive Card Support in the Smallest Package: The JP-7903A1 reads virtually every major card standard in use today — ISO14443 A/B/C (including second-generation ID cards), ISO15693, iClass, SONY, and EM4100 series — all in an ultra-compact 47mm × 26mm × 5mm footprint. This makes it the ideal choice for mixed-card environments where different card technologies are deployed across different buildings, regions, or user groups, while fitting into the tightest enclosures.

• iClass and ISO15693 Support in a Space-Saving Design: Supporting both iClass (HID's enterprise credential standard) and ISO15693 (long-range applications), the JP-7903A1 enables integration with enterprise access control systems and long-range applications such as parking access and logistics — without requiring additional hardware or larger enclosures.

• Ultra-Compact Design for Slim Products: At just 47mm × 26mm × 5mm with integrated antenna, the JP-7903A1 fits into the most space-constrained devices — slim readers, flush-mount keypads, fingerprint terminals, and compact access control panels where larger modules simply won't fit. This enables modern, aesthetically pleasing product designs without compromising on card compatibility or read performance.

• Extended Read Range in a Compact Form Factor: Despite its ultra-compact size, the JP-7903A1 delivers >8cm read range for ISO15693, iClass, and EM4100 cards — matching the performance of much larger readers. This means users benefit from forgiving card positioning and fast entry, even in slim-profile devices.

• OEM Customization for Seamless Integration: Full OEM customization support means the JP-7903A1 can be tailored to specific voltage, interface, form factor, and feature requirements — enabling seamless integration into existing product lines without hardware redesign, while the ultra-compact form factor provides maximum flexibility for space-constrained designs.
