2. When installing more than two readers side by side or back to back
The read range may get reduce if more than two readers are installed side by side or back to
back. Also, when a card is presented to one of the readers, the other reader may wrongly
recognize the card as well. To prevent such interference, make sure the distance between
readers is at least 20cm.
