MetraTec Quasar RFID Reader (COM3) Driver

The MetraTec Quasar RFID Reader (COM3) driver helps Windows recognize the Metratec USB RFID reader and allows compatible software to communicate with it through a serial COM port. It is intended for users setting up the reader for the first time, restoring a missing connection, or troubleshooting a device that appears with a warning in Device Manager.

Key Features

• USB communication support: Provides the driver connection needed for compatible RFID applications to access the reader over USB.
• COM-port access: Lets software communicate with the reader using its assigned serial port. Although the device name includes COM3, Windows may assign a different port on your computer.
• Support for listed Windows systems: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility details of the selected driver package.
• Device recognition: Installing the appropriate driver can help resolve recognition problems caused by a missing or incorrectly installed driver.

How to Install MetraTec Quasar RFID Reader (COM3) Driver

1. Check your Windows configuration. Confirm your Windows version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported; Windows 11 compatibility is not confirmed here.
2. Choose a compatible package. Before starting your MetraTec Quasar RFID Reader (COM3) driver download for Windows, verify the package’s supported operating systems and hardware details. Choose the latest version that explicitly supports your setup, and use a trusted source when selecting a free download.
3. Install the driver. Extract the downloaded archive if necessary. Run the included installer and follow its instructions, including any guidance on when to connect the reader.
4. Use Device Manager if needed. If the package has no installer, connect the reader, locate it in Device Manager, select Update driver, and browse to the extracted driver folder.
5. Confirm the connection. Check Device Manager for the reader’s assigned COM port and any warning icons. Select that same port in your RFID software, then test communication using the application’s instructions.

Keep the driver updated when Metratec provides a compatible release that addresses your needs. Before you update a working installation, review the package notes and retain the previous installer in case you need to restore your existing configuration.
