Interface Card ACS ACM1252U-Z2

The Interface Card ACS ACM1252U-Z2 is a compact USB 2.0 NFC reader module operating at 13.56 MHz, designed for easy integration into embedded and compact systems. It supports ISO 14443 Type A and B cards, MIFARE®, FeliCa, and ISO 18092–compliant NFC tags, and provides a proximity reading distance up to 30 mm depending on the tag. The device is PC/SC-compliant, firmware-upgradeable and certified (CE, FCC, Microsoft WHQL), making it suitable for reliable cross-platform use.

Advantages

Small form factor (20 × 52 × 6 mm) allows integration into compact machines and devices. Supports multiple contactless standards (ISO 14443 A/B, MIFARE, FeliCa, ISO 18092) and NFC peer devices with data rates up to 424 kbps. Anti-collision handling ensures only one card is accessed when multiple cards are present. USB 2.0 interface and detachable micro-USB cable provide flexible placement relative to the USB host. Certified compliance and firmware upgradability improve interoperability and long-term maintenance.

Suitable for (tasks / use cases)

• Integration into embedded systems and compact terminals
• Access control and secure authentication systems
• Cashless payment or transit terminals using MIFARE or FeliCa
• NFC tag reading and peer-to-peer NFC testing

How to use

Connect the ACM1252U-Z2 to a host via the USB 2.0 micro-USB cable and install the appropriate PC/SC drivers for the target operating system. Place a compatible ISO 14443 or ISO 18092 NFC tag or card within the reader’s proximity field (up to ~30 mm depending on tag) to enable communication. Use standard PC/SC or platform-specific APIs to send commands, read or write data, and manage sessions. For peer-to-peer NFC operations, follow the NFC protocol stack supported by the host application.

Usage recommendations

For best performance, place tags and cards close to the reader surface and test with the specific card types used in your application to verify read range and speed. Keep firmware updated to maintain compatibility and security.
