Abstract

In order to produce the card body from a plastic material, the electronic module (14) whose covering (50) has an undercut (54), is placed in a mould (60,62). The module is held in place by suction (72). The plastic material is injected into the mould, thereby producing a moulding around the electronic module. <IMAGE>
