BFKK ACR122U NFC Card Reader Writer

The BFKK ACR122U is a USB contactless smart card reader and writer designed for developers and system integrators working with NFC applications. It supports ISO 14443 Type A and B cards, Mifare Classic, NFC tags, and FeliCa technology. The device includes a software CD and three NXP Mifare1 S50 test cards for immediate development and testing.

USB CCID Plug-and-Play Installation

This reader operates as a USB full-speed device at 12 Mbps and complies with the CCID standard for driverless installation on most modern operating systems. Simply connect the reader to an available USB port and install the middleware or SDK from the included CD. Common issues arise when the correct PC/SC middleware is missing or when the SAM slot configuration is required but not enabled in the application layer.

106 to 242 Kbps NFC Throughput

The reader communicates with tags at 106, 212, or 242 Kbps, providing sufficient bandwidth for access control, micropayment, and ticketing transactions. It handles standard NDEF records and Mifare sector authentication comfortably. Throughput drops when processing large data payloads across multiple blocks or when the host application introduces latency via unoptimised polling loops. An optional ISO 7816-3 SAM slot adds cryptographic security for high-assurance deployments.

Questions about this item

How can I verify the ACR122U is reading tags at the stated 242 Kbps after setup?

Use the included NFC Tools GUI software to perform a read operation; the utility reports the active data rate so you can confirm 106, 212 or 242 Kbps performance.

What comes in the box and what must I purchase separately?

The package contains the ACR122U reader, a software and manual CD, and three NXP Mifare1 S50 test IC cards; no extra items are required for basic operation.

Should I choose the version with the ISO7816-3 SAM slot or the standard model?

Select the SAM-slot variant only if your application needs an additional secure-access module for enhanced cryptographic operations; otherwise the standard reader handles ISO 14443 A/B, NFC and FeliCa tags.
