Abstract
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.
