Usage and precautions

1 How to use/install

① Connect one end of the data cable to the corresponding interface of the computer, and the other end to the communication port of the card reader, and the card reader starts to enter self-test and initialization from a "beep";

② When the indicator light of the card reader is "red", it means that the card reader is in the waiting state for card swiping.

Note: Test the method of reading the label by the card reader: Open the output software of the computer (such as editors such as Notepad\WORD\EXCEL), put the card close to the card reader, and the label card number will be displayed at the cursor of the output software.

2 How to detect the card reader connected to the computer

The card reader enters the card swiping state, open the "Device Manager" of the computer, and check whether there is a person in the options menu.

Physical input device, if it appears, it means that the device has been successfully connected to the computer.

3 Precautions and Simple Troubleshooting

    ØIf the data cable is directly inserted into the charging plug, the card reading will be unsuccessful.
    Ø There are many factors that affect the card reading distance. Different protocols, different antenna designs, surrounding environments (mainly metal objects) and different cards will affect the actual card reading distance.
    Ø If the reading distance of the card reader is too long, it will cause the card reading instability or failure, and avoid reading the card in a critical state (the distance that can just read the card). Two card readers that are too close at the same time will interfere with each other.
    Ø For the card reading method, it is recommended to use the card to face the card reader and approach it naturally. The card reading method of quickly swiping the card from the side is not advisable, and the success of the card swiping is not guaranteed.
    Ø When swiping the card, it is recommended not to operate the mouse to avoid errors in data transmission.
    ØThe length of the communication cable between the card reader and the computer should be less than 15 meters.
    Ø There is no response when swiping the card: whether the interface is plugged in properly; whether the radio frequency card is a corresponding RFID Card; whether the radio frequency card is damaged; whether another radio frequency card is within the reading range.
    Ø Data transfer error: whether the mouse is operated when swiping the card; whether the card is read in an environment with strong electromagnetic field interference; whether the communication cable between the card reader and the computer is too long; whether the card is read in a critical state.
