Abstract: A system and a method for securing electric apparatus, that includes at least one transmitter transmitting at least one coded signal, and where the system includes at least one electric apparatus interacting with at least one decoder. To prevent electric apparatus from being used in other places than where intended, a one-way communication system causes the apparatus to lose their practical value if they are stolen. Activation of the electric apparatus is conditional on the transmitter transmitting a coded signal to at least one decoder that receives the coded signal and interacts with at least one electronic switch for establishing power supply to the apparatus. By using a device that switches off the power supply or other essential electric circuit for the electric apparatus in case that the decoder does not receive and decode the transmitted signals, it is possible to protect electric apparatus very efficiently against theft.
