ACS - ACM1552U-Y3

In a wide range of modern identification, authentication, and transaction-driven applications, compact and flexible HF | NFC RFID reader modules form the technological backbone of secure and user-friendly systems. The ACS ACM1552U-Y3 USB NFC Reader Module with detachable antenna is designed around 13.56 MHz contactless technology and delivers a future-proof solution for embedded and desktop environments alike. As an NFC Forum–certified NFC III reader, it supports the most relevant HF standards, including ISO/IEC 14443 Type A and Type B, ISO/IEC 15693, and ISO/IEC 18092 (NFC). This comprehensive standards coverage ensures seamless interoperability with common NFC cards, tags, and devices, making the ACM1552U-Y3 a strong choice for organizations that need to support diverse credential types across multiple applications and deployment scenarios.

The ACM1552U-Y3 has been developed with system integration and flexibility as key design principles. As a USB-based, plug-and-play NFC reader module, it is compliant with both CCID and PC/SC standards, allowing straightforward integration into existing IT infrastructures without the need for proprietary drivers. High-speed data communication of up to 848 kbps ensures responsive interactions and fast transaction processing, which is essential in environments with frequent card usage or time-critical workflows. The module also supports USB firmware upgradeability, enabling long-term maintenance, feature updates, and lifecycle optimization without hardware replacement. Together with support for extended contactless APDU commands, the ACM1552U-Y3 provides developers with the flexibility required for advanced NFC applications and customized system logic.

A key differentiator of the ACM1552U-Y3 is its detachable antenna design, which significantly expands deployment options compared to fixed-antenna reader modules. This architecture allows the antenna to be positioned independently from the main electronics, making it easier to integrate the reader into space-constrained housings, custom enclosures, or complex mechanical designs. As a result, the module is well suited for applications such as smart displays, industrial automation systems, point-of-sale terminals, and point-of-care devices, where antenna placement is critical for reliable read performance and optimal user interaction. In addition, the reader supports the three core NFC operating modes—reader/writer, card emulation, and keyboard emulation—which enables a single hardware platform to cover multiple functional roles within a product portfolio or across different customer requirements.

From a security and scalability perspective, the ACM1552U-Y3 is designed to meet professional and institutional demands. The module can optionally be equipped with a SAM slot compliant with ISO/IEC 7816, allowing the use of Secure Access Modules for enhanced cryptographic operations, protected key storage, and higher transaction security. This option makes the reader particularly attractive for government, healthcare, and enterprise applications where compliance, data protection, and trust are paramount. At the same time, the compact form factor and cost-effective design make it suitable for high-volume deployments without compromising performance or reliability. At IDCRAFT, we support customers in selecting, configuring, and integrating ACS HF | NFC RFID reader modules into their systems—covering antenna concepts, security architectures, and application-specific requirements. For organizations seeking a versatile, standards-compliant, and integration-friendly USB NFC reader module, the ACM1552U-Y3 offers a balanced and future-ready foundation for a wide range of contactless solutions.
