The wire diameter is recommended to be more than 0.3 Square millimeters. The can not exceed 100 meters. The shield wire is connected to the GND of the controller. The card reader is installed on a metal. Since the card reader is a radio frequency product, the metal pair near the front or the rear absorb its radio frequency signal. If the metal is large, it even affect the card reader. Card, or the reading distance is very attenuated. The distance between the two card also affect the card reader, some shorten the card reading distance, and some cause the two card to read the card at the same time or the card reader cannot read the card.
