Note:
1. If the reading distance of the card reader is too long, it will cause the card reading to be unstable or fail. Avoid reading the card in a critical state (the distance just to be able to read the card). At the same time, two adjacent card readers will also interfere with each other.
2. 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.
3. The way to read the card, it is recommended to use the card is facing the reader naturally close, with the card from the side quickly across the card reading method is not desirable, do not guarantee the success of the card.
4. There is no response when swiping the card: Whether the interface is inserted properly; whether the radio frequency card is a label corresponding to the protocol; whether the radio frequency card is broken; whether another radio frequency card is in the card reading range.
