An electronic payment card includes a support of standardized thickness and an electronic module having a semiconductor component, the module being designed to be incorporated in the support. The electronic module is included in a miniature card of thickness equal to the standardized thickness, the support having an opening for receiving the miniature card. The opening and the miniature card have complementary parts for removably installing the miniature card in the opening and suitable, firstly, for preventing the miniature card from being positioned incorrectly in the opening and, secondly, for integrating the miniature card exactly in the thickness of the support. The card is applicable to the field of electronic transactions requiring the use of a memory card.

Electronic payment card with an interchangeable module

A card comprising an electronic module having a memory, into which a designated number of consumable units has been stored, and a metal electrical contact zone. At least one part of the contact zone is covered with a layer of readily removable material which is applied before the card is delivered to points of sale. This material must be removed to enable the card to be read. Once having been removed, the material indicates that the card has been used so that consumer fraud can be prevented in terms of the number of consumable units retained in the memory.
