Promag PCR-310 USB RFID Reader/Writer 13.56 MHz (ISO14443, MIFARE), USB

Reading and writing contactless smart cards at 13.56 MHz often means wrestling with driver installations and proprietary software. The Promag PCR-310 USB RFID Reader/Writer eliminates that friction: plug it into any USB port and it enumerates as a standard HID keyboard or virtual COM port, so your existing applications can capture card data immediately.

Who is it for

Access control integrators, time & attendance developers, loyalty program operators, and anyone building contactless identification into Windows, Linux, or macOS systems. The PCR-310 handles MIFARE Classic, Ultralight, DESFire, FeliCa, and NTAG tags, covering the most common credential ecosystems.

Tips

For quick testing, switch the reader to HID mode and open any text editor—scanned card UIDs will appear as keystrokes. When integrating with existing software, use the virtual COM port mode and the provided SDK to access full read/write functionality. Keep the reader away from metal surfaces, which can detune the antenna and reduce read range.
