Title
(EN) Magnetic code comprising a reading base and reading system thereof
Abstract
(EN) The invention concerns a magnetic code (1) and a reading system thereof, the code (1) comprising magnetic encoding elements (Ci) and magnetic reference elements (Bi) forming a code reading base (BA). The associated reading system comprises components with magnetoresistance for sensing the encoding elements and the code reference elements.
