Introduction
This instruction manual provides essential information for the proper setup, operation, and maintenance of your Nedis CRDRU2SM3BK Smart Card ID USB 2.0 Card Reader. Please read this manual thoroughly before using the device to ensure optimal performance and safety. This device is designed for reading smart cards, commonly used for identification, secure login, and digital signatures on desktop computers.
Setup
- Unpack the Device: Carefully remove the Nedis CRDRU2SM3BK Smart Card Reader from its packaging. Ensure all components, including the card reader and USB cable, are present.
- Connect to Computer: Plug the USB connector of the card reader into an available USB 2.0 port on your desktop computer. The device is designed for desktop use.
- Driver Installation:
- For most modern operating systems (Windows 10/11, macOS, Linux), the device should be recognized automatically as a Plug-and-Play device, and drivers will install without user intervention.
- If automatic installation does not occur, or if you are using an older operating system, insert the provided driver CD (if included) into your computer's optical drive and follow the on-screen instructions to install the 'Smart Card Driver'. Alternatively, visit the official Nedis support website to download the latest drivers for your model.
- Verification: After driver installation, check your computer's Device Manager (Windows) or System Information (macOS) to confirm that the 'Smart Card Reader' is listed and functioning correctly.
Operating Instructions
- Insert Smart Card: Gently slide your smart card (e.g., ID card, bank card, digital signature card) into the card slot of the Nedis CRDRU2SM3BK. Ensure the chip on the card faces upwards and is inserted fully until it clicks into place or reaches the end of the slot. Refer to the arrow indicator on the device for correct insertion direction.
- Access Card Data: Once the card is inserted, your computer's operating system or specific smart card applications will detect the card. You can then use compatible software to read data from the card, perform secure transactions, or authenticate your identity.
- Remove Smart Card: When you have finished using the smart card, gently pull it out from the slot. Avoid forcing the card to prevent damage to both the card and the reader.
Maintenance
- Cleaning: To clean the exterior of the card reader, use a soft, dry, lint-free cloth. Do not use liquid cleaners, aerosols, or abrasive materials, as these can damage the device.
- Storage: When not in use, store the card reader in a clean, dry environment, away from direct sunlight, extreme temperatures, and excessive dust.
- Handling: Avoid dropping the device or subjecting it to strong impacts. Do not attempt to open the casing, as this will void the warranty.
Troubleshooting
- Device Not Recognized:
- Ensure the USB cable is securely connected to both the card reader and the computer.
- Try connecting the card reader to a different USB port on your computer.
- Restart your computer.
- Verify that the correct drivers are installed. Reinstall drivers if necessary.
- Smart Card Not Reading:
- Ensure the smart card is inserted correctly with the chip facing upwards and fully seated in the slot.
- Check if the smart card itself is clean and undamaged. Clean the card's chip with a soft, dry cloth if needed.
- Test with a different smart card if available to rule out a card issue.
- Ensure your smart card application software is running and configured correctly.
- Slow Data Transfer:
- The device operates at USB 2.0 speeds (up to 480 Mbps). Ensure it is connected to a USB 2.0 or higher port for optimal performance.
