Abstract: A fail recovery method and an Internet of Things (IoT) system and a charging system using the same are provided. The fail recovery method includes following steps: providing a plurality of gateway devices, in which at least one of the gateway devices preset to provide a wireless network service to at least one IoT device and at least another one of the gateway devices preset to provide the wireless network service to at least one user device; mutual confirming an operation state of other one of gateway devices by the gateway devices; and when the one of the gateway devices is determined as failed, using the another one of the gateway devices to replace the failed gateway device, so as to simultaneously provide the wireless network service to the IoT device and the user device by the another one of the gateway devices.

Abstract: A method for automatically establishing a wireless connection, a gateway device and a client device for internet of things (IoT) using the same are provided. According to the provided method, SSID of the gateway device can be composed of an encrypted access password and an index, so that the client device may identify the gateway device to be connected according to the index within the SSID string and acquire the encrypted access password from the SSID string. Therefore, the client device can decrypt the encrypted access password. Accordingly, the wireless connection between the client device and the gateway device can be automatically established since the client device acquires the access password from the SSID of the gateway device.

Abstract: An identity verification method, an IoT gateway device, and a verification gateway device using the same are provided. According to the provided method, the IoT gateway device firstly establishes a look-up table including a valid MAC address list and a valid RSSI range of at least one valid client device. When the IoT gateway device receives the connection request sent from the client device, the IoT gateway device may obtain the MAC address and a RSSI value of the client device according to the connection request and compare the received MAC address and the received RSSI value with the valid MAC address list and the valid RSSI range, so as to determine whether the client device is the valid client device.
