★Product Introduction:
Crafted with organic glass buttons that never wear out, this product incorporates a microelectronic RF receiver module and an embedded microcontroller, combined with efficient decoding algorithms and advanced data processing technology. As an external input device for computers, this card reader can read the serial number from an RFID card and output it to the computer via PS/2, akin to automatic keyboard number entry. It allows for recording card numbers using common software such as Microsoft Word and Notepad, offering reliable performance and convenient operation. The card numbers recorded can be used to derive more management functions.

★Installation Instructions:
Connect the USB cable. When the card reader beeps twice and the green light flashes twice, it indicates successful installation. You can test it using common software such as Microsoft Word or Notepad. Open Word or Notepad and ensure it is in input mode. Swipe the card, and if the reader beeps once and the green light flashes once, a series of numbers will appear in Word or Notepad followed by an automatic carriage return. This indicates that the system is functioning normally. The numbers displayed are the serial number of the RFID card required.

★Precautions and Simple Troubleshooting:
●1. Install the card reader in a location that is convenient for card swiping operations, while avoiding proximity to monitors, as monitor radiation may interfere with the normal operation of the card reader.
●2. It is recommended not to operate the mouse while swiping the card to avoid errors in data transfer.
●3. The length of the communication cable between the card reader and the computer should be less than 15 meters.
●4. Avoid swiping cards at the critical distance (the minimum distance just enough to read the card).
●5. Check if the USB cable is properly connected.
●6. If there is no response when swiping the card: Check if the interface is properly plugged in; Verify if the RFID card is compatible; Confirm if the RFID card is damaged; Ensure no other RFID card is within the reading range.
●7. If there are errors in data transfer: Check if the mouse was operated while swiping the card; Confirm if the card was read in an environment with strong electromagnetic interference; Verify if the communication cable between the card reader and the computer is too long; Ensure the card was not read at the critical distance.
