The ACS USB CCID Smart Card Reader from ACS COMPRO connects compatible smart cards to your PC through USB. Its driver allows Windows and supported smart-card software to communicate with the reader for tasks such as certificate-based sign-in, digital signing, and identity verification. Select the driver package that matches your version of Windows 11, 10, 8, or 7 and your system architecture.

Key Features

• USB CCID communication: Provides the connection between the reader and Windows using the Chip Card Interface Device standard.
• Smart-card software integration: Enables compatible applications to access the reader through Windows smart-card services. Some cards may also require separate middleware or certificate software.
• Device recognition: Helps Windows identify the ACS USB CCID Smart Card Reader and make it available to applications that use smart-card authentication.
• Windows driver options: Supports installation on Windows 11, 10, 8, and 7 when you choose a package intended for your operating system and hardware.

How to Install

1. Check your Windows configuration. Open your system information to confirm the Windows version and whether your installation is 32-bit or 64-bit. Verify that the selected driver package lists your reader and operating system.

1. Download and prepare the driver. Save the compatible package to your computer. If it is a compressed archive, extract its contents before continuing. Close any applications currently using the smart-card reader.

1. Run the installer. If the package includes a setup program, launch it and approve the administrator prompt when requested. Follow its instructions about when to connect or disconnect the reader.

1. Use Device Manager if necessary. For a package without an installer, connect the reader, open Device Manager, and locate it under Smart card readers or Other devices. Right-click the device, choose Update driver, then browse to the extracted driver folder.

1. Confirm operation. Restart Windows if prompted, then check that the reader appears in Device Manager without a warning icon. Insert a compatible smart card and test it with your intended application.

If Windows recognizes the reader but your application cannot use the card, check the application’s middleware and certificate requirements. A working reader driver does not replace card-specific software, credentials, or access permissions.

Common Issues and Fixes

• Install fails or rolls back: Run the ACS driver installer as administrator, match it to your Windows version/architecture, and unplug the reader until installation finishes. If Windows blocks the driver, install the signed ACS/CCID package rather than forcing an unsigned one.
• Device not detected: Check Device Manager for “Unknown device” or errors under Smart card readers. Try another USB port without a hub, reseat the cable, and confirm the Windows Smart Card service is running.
• Version conflicts: Remove older ACS/CCID drivers and vendor smart-card middleware, reboot, then install the latest package. Avoid mixing the Windows generic CCID driver with ACS middleware unless ACS documentation specifies it.
