The present application provides a wireless charging module and a modularized sensing device therewith. A first charging unit is disposed around the inside of the wireless charging module for wirelessly charging a sensing module. Without introducing a transmission line as an electricity transmitting medium, the sensing module can be directly disposed inside and charged by the wireless charging module, which improves flexibility of implementation. Further, since the first charging unit is configured to surround the inside of the wireless charging module shaped as a bowl structure, the sensing module can be simply disposed into the bowl structure and wirelessly charged by the surrounding first charging units, which saves the inconvenience of setting the sensing module to a specific location or area for stable wireless charging and increases effective charging angles.

An anti-counterfeiting RFID tag structure includes a body and a RFID device disposed on the body. The body is an O-ring. The RFID device includes a RFID chip circuit and an antenna structure. The anti-counterfeiting RFID tag structure is disposed fully between the cap and the opening of the bottle container whenever the bottle container is sealed. A user reads anti-counterfeiting ID code and product curriculum vitae data stored in the RFID device, using a stationary or handheld RFID reader, so as to effectuate identification and anti-counterfeiting.

An electronic seal includes a radio frequency identification apparatus, an antenna assembly and an impedance matching circuit. The radio frequency identification apparatus includes at least two radio frequency identification units each for providing a specific code for identification. The antenna assembly is electrically connected to the radio frequency identification units. The antenna assembly is used to receive an electromagnetic signal for identification to excite the radio frequency identification units to transmit the specific codes through the antenna assembly. The impedance matching circuit is provided between the radio frequency identification units and the antenna assembly for adjusting the impedance matching of the radio frequency identification units to the antenna assembly, thus adjusting excitation powers and feedback powers of the specific codes from the radio frequency identification units through the antenna assembly.

An alternate radio transmitter includes a processor, a modulator, a PLL unit and a radio transmission unit. The processor provides a digital signal. The modulator modulates the digital signal, thus providing at least two modulated signals. The PLL unit mixes the modulated signals, thus providing an output signal. The radio transmission unit transmits the output signal.
