Surveillance of magnetically tagged articles in a control zone is effected in a noisy environment by so shielding an antenna establishing a front magnetic field in the control zone as to reduce field strength in the back field rearwardly of the control zone. Shield magnetic material has response to the field which is detectably distinct from tag material response to the field.
