A: Yes, but only if you write custom software that accesses the reader in raw serial mode. The keyboard emulation mode outputs only the UID, not the card’s stored data. To read data blocks from a MIFARE card and write them to another compatible writable card, you need full command‑level access, which requires the proprietary command set from the manufacturer.
: You can use the reader with basic text-based programs such as Microsoft Excel , Notepad , or Word to capture card data. How to Use the Device
You can open Notepad (Windows), TextEdit (macOS), Gedit (Linux), or a terminal window, tap the card on the reader, and see the UID appear immediately. This is why many users believe there is no “r20xcusb software” at all—they are already using the device successfully with basic operating system features.
Since the device mimics a keyboard, you don't need complex APIs or DLLs. You simply need to: to a specific input field in your UI. r20xcusb software
: Sometimes mistakenly associated with "Rockchip" USB drivers (rockusb.sys) or specialized industrial utilities like "Revealer," though these are unrelated to the RFID reader. Software
While the device works out of the box, the specialized (often a "ConfigTool" or "R20C Reader Setup" program) is essential for advanced functionality. The default behavior is to output the card ID in a decimal format, but the software allows for significant customization. Key Functions of the Software:
: Launch the application. If it fails to identify the hardware, right-click the executable file and select Run as Administrator . A: Yes, but only if you write custom
The software cannot find the vendor ID (VID) or product ID (PID) associated with the reader chip.
While it supports Windows 7, 8, 10, and 11, it is best suited for scenarios requiring simple, straight-to-text input rather than complex cryptographic card reading.
: Adjust output configurations to recognize varying regional keyboard standards, ensuring string readouts do not drop characters. : You can use the reader with basic
Since the R20XCUSB is a 125KHz or 13.56MHz (depending on the specific sub-model) device, software like NFC Tools or proprietary manufacturer SDKs allow users to view internal data blocks and write new information to compatible tags. 2. Primary Use Cases Users typically employ this software for:
In the software interface, choose your desired output format from the dropdown menu.
: Change your parameters (e.g., changing from 10-digit decimal to 8-digit hex) and click Write or Set . The reader will emit a prolonged beep confirming that the new structure has been successfully written to its onboard EEPROM memory. Technical Specifications Summary
: Upon connection, the built-in buzzer will sound, and the LED will turn red , indicating the device is in standby mode. Verification :
, meaning it translates RFID tag data into keystrokes. When a tag is presented, the reader "types" the card's serial number into any active text field, such as Notepad or Excel. Driverless Operation
