Usage and points for attention

     One end of the data line is connected to the corresponding interface of the computer, the other end is connected to the communication port of the card reader, and the card reader enters the self-test and initialization with the sound of "dropping". 

 When the card indicator is red, the card reader enters the waiting card state. 

     Note: Test card reader reading label method: Open the computer output software (such as Notepad WORD EXCEL and other editors), the card close to the reader, at this time the output software cursor display label card number. 

Method for detecting card reader connecting to computer

The card reader enters the card swipe state, opens the "Device Manager" of the computer, checks whether the anthropological input device appears in the menu of options, and if so, indicates that the device has successfully connected to the computer. 

Matters needing attention and Simple troubleshooting

Ø If the data connection is directly inserted into the charging plug, it will cause unsuccessful reading.

Ø There are many factors that affect the distance of reading cards. Different antenna designs, surroundings (mainly metal objects) and different cards will affect the actual distance of reading cards because of different protocols.

Ø If the reading distance of the card reader is too long, it will cause instability or failure of the card reader, and avoid reading the card in the critical state (the distance between just reading the card). At the same time, the two card readers that are too close will interfere with each other. 

Ø It is suggested that the card should be read in the direction of the card reader. It is not advisable to read the card quickly across the side of the card. It is not guaranteed that the card will be swiped successfully.

Ø When you read your card, it is recommended not to operate the mouse to avoid sending data errors.

Ø The length of the communication cable between the card reader and the computer should be less than 15 meters.

Ø If No response when read the card: whether the interface is plugged in; whether the RF card is the corresponding RFID card class; whether the RF card is broken; whether there is another RF card in the card reading range. 

Ø Data transfer error: whether the mouse is operated while swiping the card; whether the card is read in the environment of strong electromagnetic interference; whether the communication cable between the card reader and the computer is too long; whether the card is read in a critical state.
