ABSTRACT:
A receptacle for mounting data carriers or code carriers which are inductively and/or electromagnetically read and/or written and which are to be embedded flush in a metallic environment requires a minimum of discrete members and simultaneously ensures an effective energy transfer from a sender coil to the data carrier or code carrier. A prefabricated receptacle adapted to a geometry of a mounting recess in the metallic object, the receptacle is made of an injection molding and/or casting material to which materials are added to set the relative magnetic permeability .mu..sub.r of the receptacle to at least 2 or greater and its specific ohmic resistance sufficiently high (>.OMEGA..multidot.m), the receptacle entirely encases the data carrier or the code carrier and further components, if any.
