Abstract (en)
[origin: WO0163554A2] The invention relates to a marking device (1, 11) for the identification of objects, comprising a coding consisting of areas (4, 5, 13) of differing magnetic properties. The marking device is characterized in that the magnetic areas (4, 5, 13) are magnetically biased in such a way that their hysteresis loops (7, 8, 15) are displaced on the field strength axis (H) in relation to the progression which is symmetrical to the magnetisation axis (M). The invention also relates to a method and apparatus for producing a marking device of this type and to a method for reading the same.
