The invention provides a safety reading-writing method and system, and relates to the technical field of the Internet. The method specifically comprises the steps that a monitor is used for monitoring in real time whether a reader-writer receives an external card swiping signal or not, wherein the periphery of the reader-writer is wrapped by a magnetic wave filtering housing which is used for shielding an electromagnetic wave generated when a user uses a card; therefore, a controller controls a charging unit to complete the charging after the monitor monitors that the reader-writer receives the card swiping signal, thereby effectively solving a problem of charging errors caused by the unlocking/locking failure in a code scanning mode during network delay, and improving the user experience. 本申请提供了安全读写方法及系统，涉及互联网技术领域，其中，该安全读写方法具体包括：监控器用来实时监测读写器是否接收到外界的刷卡信号，其中，在读写器的外围包裹有磁波过滤壳，用以屏蔽用户使用卡片的电磁波，这样，控制器在监控器监测到读写器接收到刷卡信号后控制计费器完成计费，从而有效避免了扫码方式下因为网络延时造成开锁/关锁失败而造成计费错误的问题，进而提高了用户的体验度。
