<p>The device (10) has a card body (12) forming a medium for contactless electronic labels (14A, 14B), where the body is made of plastic material. The labels have near-field electronic communication units (20A, 20B) activated by applying magnetic field (B). The labels have magnetic shielding units arranged between a face of the body and one communication unit and between another face of the body and another communication unit such that application of the field to one of the faces activates only one communication unit. The shielding units have a ferrite layer. An independent claim is also included for a method for manufacturing an electronic device.</p> |
