    摘要: A transponder has a memory, a data processor, a transmit memory and a transmission circuit. The memory stores data. In a transmit mode of the transponder, the data processor is operable in a normal-energy mode and an energy-saving mode. When the data processor is in the normal-energy mode, the data processor retrieves the data from the memory and processes the data, and the processed data is stored in the transmit memory. Thereafter, the data processor is controlled from the normal-energy mode to the energy-saving mode, and the transmission circuit reads out the stored processed data from said transmit memory and transmits the read out stored processed data to a base station.
