JP-7903A2 Card Reader Module

 

Product Overview

     The JP-7903A2 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-7903A2 offers three interface options (Wiegand with TTL customization, UART, and USB) and is housed in a slim 80mm × 28mm × 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 advanced 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 where national ID reading is required.

• 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.

• Compact Integrated Antenna Design: Measures only 80mm × 28mm × 5mm with built-in antenna — fits easily into 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 Available: The JP-7903A2 reads virtually every major card standard in use today — ISO14443 A/B/C (including second-generation ID cards), ISO15693 (for long-range applications), iClass (HID's enterprise credential standard), SONY, and EM4100 series. This makes it the ideal choice for mixed-card environments where different card technologies are deployed across different buildings, regions, or user groups. One module covers everything — no need to stock multiple reader types.

• iClass Support for Enterprise Access Control: iClass cards are widely deployed in enterprise, government, and campus access control systems. The JP-7903A2's support for iClass cards enables integration with these existing systems without additional hardware, simplifying upgrades and migration to newer card technologies while maintaining compatibility.

• Extended Read Range for ISO15693 and iClass: With >8cm read range for ISO15693 and iClass cards, the JP-7903A2 provides more forgiving positioning than standard readers. This means faster access in high-throughput environments — users tap cards without precise alignment, reducing bottlenecks and improving the overall user experience at busy entry points.

• Flexible Integration with OEM Customization: The combination of Wiegand (with TTL customization), UART, and USB interfaces provides universal connectivity across diverse host platforms. Additionally, full OEM customization support means the module can be tailored to specific voltage, interface, and form factor requirements — enabling seamless integration into existing product lines without hardware redesign.

• ISO15693 Support for Long-Range Applications: ISO15693 cards (such as NXP ICODE series) are used for long-range applications where the card does not need to be precisely positioned — for example, parking access, logistics, and inventory management. The JP-7903A2's support for ISO15693 enables these applications alongside standard access control cards in a single module.
