- Connect to Computer: Plug the USB cable of the reader into an available USB port on your computer. The device is driver-free and plug-and-play, so no additional software installation is needed.
- Initialization: Upon connection, the card reader will perform a self-test and initialization. You will hear a "drop" sound, and the indicator light on the reader will turn red, signifying it is ready for use.

5. Operating Instructions
- Prepare Your Software: Open any text-editing or data-entry software on your computer where you wish the card number to appear. Examples include Notepad, Microsoft Word, Excel, or a custom application. Ensure the cursor is active in the desired input field.
- Present the Card: Hold a compatible 125kHz ID card or key fob close to the 5YOA IDRead02 RFID Reader.
- Read Confirmation: As the card is read, the red indicator light on the reader will briefly flash green and then return to red. Simultaneously, the built-in buzzer will sound, confirming a successful read.
- Data Output: The card's serial number will automatically be typed into the active cursor position on your computer screen, just as if you had typed it manually using a keyboard.


6. Care and Maintenance
- Cleaning: Use a soft, dry cloth to clean the surface of the reader. Avoid using abrasive cleaners, solvents, or harsh chemicals.
- Storage: Store the reader in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Handling: Handle the device with care. Avoid dropping it or subjecting it to strong impacts.
- Cable Care: Do not bend or crimp the USB cable excessively. Ensure the cable is not under tension when connected.
7. Troubleshooting
- Reader not recognized by computer:
- Ensure the USB cable is securely plugged into both the reader and the computer.
- Try connecting the reader to a different USB port on your computer.
- Test the reader on another computer to rule out a computer-specific issue.
- No data output when swiping a card:
- Verify that the indicator light on the reader is red, indicating it's ready.
- Ensure you are using a compatible 125kHz ID card (e.g., EM4100, TK4100). The reader does not support all 125kHz chips, nor does it support 13.56MHz cards.
- Make sure an application (like Notepad or Word) is open and the cursor is active in a text field.
- Try swiping the card closer to the reader or at a slightly different angle.
- Incorrect card number output:
- Confirm the card type is supported.
- Ensure no other applications are interfering with keyboard input.
