Problems solved by technology

[0022] The known solutions described above have various advantages, however, none of these solutions allow the continuous manufacturing of contact-type microcircuit cards in a format more equivalent to the 3FF format, without involving the electronic process at the manufacturing method stage. Outlined windows or cutouts in the module supply strip and / or in the card body supply strip

Embodiment Construction

[0065] figure 1 Three bands are shown in a schematic manner, based on the three bands formed as in figure 2 Contact type cards in rolls obtained at the output of the machine shown.

[0066] A first strip, referenced 10 , comprises a continuous (that is to say without breaks outside the positioning holes, referenced 10A, especially near the longitudinal edges) support film 11 ; this support film is electrically insulating.

[0067] Formed on this support film are contact surfaces marked 12; each of these contact surfaces is formed by a plurality of contact areas defined in practice at least in part by a standard such as ISO standard 7816 provided by the given pattern; in fact, it is by means of these contact areas that the future microcircuit card will communicate with the outside by means of a card reader.

[0068] From image 3 It can also be seen that, image 3 Showing a portion of belt 10, each contact surface has at least six contact areas, corresponding to areas C1 t...

Abstract

The method involves preparing a continuous support band having a width that is same as the width of an electrically insulating band (10). A network of cavities is provided with a geometry that is as same as the geometry of a network of integrated circuits of the insulating band. A portion of the support band is provided with the set of cavities. The network of integrated circuits is located in the set of cavities. The support band is rolled by a roller (80) so as to partially cut a set of contact type microcircuit cards i.e. smart card. An independent claim is also included for a machine for manufacturing a longitudinal series of contact type microcircuit cards.

Description

technical field [0001] The present invention relates to a method of manufacturing a small format microcircuit card (or "chip card") having a format smaller than the standardized Format (see standard ISO7816), which is the usual format for bank cards; this card has a length of 85.6 mm, a width of 54 mm and a thickness of 0.76 mm. Background technique [0002] Among these smaller formats, it is especially possible to cite: [0003] -Format ID-000 (or "Plug-in-SIM") widely used for identification cards customized by mobile phone operators; also known as 2FF format; its length is 25mm, width is 15mm and thickness is 0.76mm, [0004] - A format called "mini-UICC" or 3FF; its length is 15 mm, its width is 12 mm and its thickness is approximately 0.76 mm. [0005] Recently, a format called 4FF (12.3 mm in length, 8.8 mm in width, and 0.67 mm in thickness) smaller than the 3FF format has been proposed. [0006] Microcircuit cards of the "touch" type generally comprise: a card bod...
