Engineers often use the NI-VISA driver layer. Since the R20XCUSB driver creates a standard COM port, LabVIEW can interact with it using the VISA Configure Serial Port VI, sending the same byte arrays.

Some advanced users have successfully used the R20XC with middleware on Windows and Linux. The reader appears as a CCID‑compatible device, allowing it to be accessed via standard smart card APIs (such as winscard.dll on Windows or pcsc‑lite on Linux). This enables compatibility with off‑the‑shelf security software that expects a smart card reader. r20xcusb software
