Abstract

An embodiment of the invention relates to a contactless switching system and an embodiment relates to a method for encoding same with at least one sensor and at least one signal generator, where the signal generator sends at least one data sequence and the sensor receives the data sequence. In at least one embodiment, an aim is to specify a technical teaching for encoding a contactless switching system inexpensively and in a versatile fashion. To this end, at least one embodiment of the invention proposes anchoring user-implementable encoding in the checksum of the data sequence or the checksum computation code, so that the checksum which the data sequence contains is used to check the quality of the data transmission and at the same time to implement the encoding.
