According to said method, each person is allocated a mobile receiver, which contains information stored in a memory. A respective code signal is assigned to said information. One or more first transmitters transmit(s) code signals in respective areas that are spatially limited. The receiver has reproduction means for reproducing the information stored in the memory and reproduces the information upon receipt of the code signal assigned to said information. To simplify the update of the information, second transmitters transmit information signals and information concerning the assignment of code signals in spatially limited areas, said information being saved by the receivers. The ready-to-receive state of the receivers for the information signals is temporally limited and is established without the intervention of the person receiving the information. The method can thus be carried out with an extremely low energy consumption. |
