A card body comprises a first card body (ID-1 card), a second card body (plug-in card) and a third card body (mini card). The first card body has a first shape (ID-1 shape). The second card body comprises a second shape (plug-in shape). The first card body encompasses the second card body. The third card body comprises a third shape (mini shape). The second card body encompasses the third card body. The third card body has a cavity for receiving an electronic module. A first boundary separates the first shape (ID-1 shape) from the second shape (plug-in shape), and comprises a first number of apertures () and a first number of notches (and) defining a first mechanical inter-card body coupling strength (link between ID-1 cardand plug-in card). A second boundary separates the second shape (plug-in shape) from the third shape (mini shape), and comprises a second number of apertures () and a second number of notches () defining a second mechanical inter-card body coupling strength (link between plug-in to cardand mini card). A cumulated length of the first number of apertures () is greater than a cumulated length of the second number of apertures () and a cumulated length of the first number of notches (and) is lesser than a cumulated length of the second number of notches () so that the second mechanical coupling strength is greater than the first mechanical coupling strength.

The invention concerns a method of manufacturing a module intended to create a portable object with chip and antenna. The portable object comprises an antenna and a chip placed on an insulating substrate. The antenna comprises a plurality of turns. The method comprises a first step in which an insulating substrate with at least one side is provided. The method is characterised in that it further comprises a second step in which an individual housing opening in the said side is made for each of the said turns and a third step in which said antenna comprising a plurality of turns is made by placing a conducting material in each individual housing.
