Use directions
When the card is close to the reader, the red light turns green
light flashes once again become a red light, buzzer sounded a loud
said to send data, the same ID card, the gap between the two card
read less than 500 ms, not sending data. If after reading card, ID,
IC rf card is still in the induction zone, card reader will not do
any hint, nor to send data. Different ID, IC rf card into the
induction zone respectively, reader continuous read rf card and
output data.
