读卡方式属非接触读卡方式，持卡人走近自动门时，只要将卡在读卡器附近 5-15厘米 晃动一次，读卡器就能感应到有卡并将卡中的信息 卡号 发送到控制器，门禁控制器进行判断并记录，发出开门指令，控制电锁打开，并将开门信号传递给开门机，进行自动开门。 如一些场所要求在某一时间段 如晚上 采用门禁刷卡才能通过，而在另一时间段 如白天 要求自动门自动感应开门，并且在特殊情况下 如搬运东西时 又要求自动门常开而不关闭。 A键 启用红外感应自动开门 B键 改用门禁控制状态，只刷卡开门。 C键 将门与锁常开 D键 将门与锁锁死。 门禁维修预约电话 0086 021 - 51294706 (10线 E-Mail:51780@163.com.
