Embedded RFID Reader Module | Type-C USB | For Charging Piles & Kiosks

The ACM1323 series is a family of compact, embedded 13.56MHz RFID reader/writer modules designed for seamless integration into space-constrained applications like EV charging piles, vending machines, and kiosks. The series offers two interface variants: the ACM1323U featuring a driver-free USB HID (Type-C) interface for plug-and-play simplicity, and the ACM1323S utilizing a serial (UART TTL/RS232) protocol for direct microcontroller communication. Both modules support a wide range of ISO 14443 Type A cards, including MIFARE® classics and CPU cards, with a reliable read distance of up to 50mm. Their true out-of-box functionality, coupled with support for firmware upgrades and peripheral controls, makes them an ideal, future-proof solution for modern access control, payment, and identification systems.

Key Features

Dual-Interface Design: Choose between driver-free USB HID (Type-C) for direct PC connection or Serial (UART/RS232) for embedded MCU systems.
Broad Card Compatibility: Supports ISO 14443 A (Parts 1-4) cards, including MIFARE Classic®, MIFARE 1K/4K, MIFARE Plus, DESFire®, and CPU cards.
Plug-and-Play & Easy Integration: The ACM1323U requires no additional drivers on major OS. Compact form factor (73.5 x 40.0 x 5.0 mm) and comprehensive SDK (scrio.lib/.dll) accelerate development.
Enhanced Control & Security: Features user-controllable buzzer and dual-color LED. Offers an optional ISO 7816 SAM card slot (on request) for high-security applications like payment authentication.
Reliable & Upgradeable: Designed for continuous operation with an MTBF of 500,000 hours. Supports in-field firmware upgrades via USB or serial interface without hardware changes.
Multi-Platform Support: Compatible with Windows, Android, Linux, and various RTOS (via serial port).
