When the IC card is close to the Wiegand IC card reader, the red light turns to the green light and then turns red. The buzzer sounds to indicate that the data is sent. The same IC card, the interval between the two reading cards should not be less than 0.05S. Otherwise no data is sent. After reading the card, if the IC card is still in the RF card, the reader will not react, and no data will be sent. Different IC card cards enter the RF card area, and the card reader continuously reads the card and outputs data.
