Abstract: An electronic device for accessing wireless network includes a radio frequency (RF) module, a power supply management unit, a CPU and a data transmission interface. The RF module receives electromagnetic wave signal from networks and transmits electromagnetic wave signals to the networks. The data transmission interface transmits the electromagnetic wave signals from the RF module to the CPU, and transmits data and commands between the RF module and the CPU. When the electronic device does not communicate with a remote server on the networks during a predetermined time period, the CPU suspends the data transmission interface. A related method of saving resource is also provided.

Abstract: A wireless communicating electronic device includes a wireless communication unit, a shell receiving the wireless communicating unit therein, a touch sensing unit, and a processing unit. The touch sensing unit includes an antenna, a regulating circuit, and an analog-digital (AD) converting module. A given portion spatially corresponding to the antenna defined on the shell. The antenna generates an alternating current (AC) signal in response to a finger touch on the given portion. The regulating circuit regulates the AC signal. The AD converting module converts the AC signal into a digital signal. The processing unit executes an instruction in response to the digital signal.

Abstract: An electronic tag includes a screen, a barcode input interface configured for receiving a barcode, a wireless communication unit configured for sending the barcode to a host and receiving an updated content associated with the barcode code sent by and from the host, a driving unit configured for driving the screen to display the updated content. The electronic tag can rapidly and accurately get the article data that corresponds to the barcode of the article and display the content of the article data on the screen to update the original display.
