| Issue | Likely Solution | |-------|----------------| | Reader not detected | Check USB/serial connection; reinstall reader drivers. | | “Access denied” error | Run the tool as Administrator. | | No card data displayed | Verify card technology (e.g., Mifare, HID Prox) is supported by the reader. | | Firmware update fails | Connect directly to the reader (not through a USB hub). |

Use Windows Settings > Apps > Installed Apps . Remove both "Ysoft Card Reader Tool" and "Ysoft Virtual Driver." Then manually delete C:\ProgramData\Ysoft leftovers.

Can integrate with existing access control systems to manage and monitor access based on card data.

A: In the tool, go to Reader > Firmware Update > Load HEX File . Only perform this if you have the correct firmware file from your reader manufacturer (e.g., HID).
