摘要
The invention relates to a method for controlling the power supply of a mobile data memory (MDS) with a contact-free data transfer, containing at least one energy accumulator (BAT) and a consumer (P1, P2, DE, EMO, C, MEM), wherein the energy supply is lowered in a standby mode (IP, IR, IT). The data memory is ready for receiving and a receiving signal (ES) is evaluated in such a manner that at least one predetermined back-scatter frequency (f1) for a possible transmission mode and an associated communication frequency (f2) for receiving data can be detected. The energy supply of the data memory is switched on in the full operating mode (IE; IC). The invention also relates to a mobile data memory in addition to an identification system (IS) with at least one reading/writing device (SLG) and a mobile data memory. One advantage of said invention is that no extra batteries are required during the full service life of the mobile data memory.
