- the turns may extend in a plane substantially parallel to the main plane of the battery or form a spiral whose axis is perpendicular to the main plane of the battery avoiding contacts, especially above or below the contacts. .
- the fact of having a connector on the card allows to choose an antenna whose shape is adapted to the shape of the terminal in particular according to the position of the card in the terminal. Indeed, if we have from one terminal to another a rotation of 90 ° of the position of the card in the terminal, it may no longer allow an optimized placement of the antenna in the terminal without excessive torsion of the antenna or its connecting tab even if the latter is flexible.
- the antenna has the advantage with its flexibility or elasticity to be able to surround the outer surface or outer contour of the terminal; According to an alternative, thanks to its fineness and flexibility, the antenna can be arranged inside and / or outside the terminal and adapt to different existing forms of terminal.
- connection tab makes it possible to redirect the antenna at the output of the card in any discretion, in particular to pass between the housing and a flap or shutter of an insertion slot of the adapter card.
- the antenna is thus less exposed to the outside for aesthetic reasons or exposure to a possible mechanical fastening.
- the fineness and flexibility of the antenna or at least of the tongue can redirect the antenna if necessary the inside of the casing passing at the intersection or interface of the shells forming the terminal box.
- the tongue may be substantially the thickness of the wire for example of the order or less than 80 microns.
- the tongue may consist simply connecting son at least at the passages between the shells or flap and housing.

It takes advantage of a set of assembly operation or a certain elasticity of the shell to pass a portion of connecting wire of the antenna.
- the antenna can be connected to the card with or without a detachable connector although Figure 6 provides a detachable connector.
- the card can be any card including a customer identification card or an M2M module.
