Intelligent card useful in telephony and the like

摘要

Two types of subscriber identification modules (SIM) exist in the field of mobile telephony, one type conforming to the conventional ISO 7810/13/16 format and the other type to the PrENV 1375-2 European pre-standard format. In particular, the latter type uses a small identification module on its own, and the first type uses such module integrally with a larger plastic card. The intelligent card of the invention is comprised by the combination of a module (1) conforming to the European pre-standard and a laminar sheet (2) having a window (3) capable of housing therein said module (1) snugly to turn into a chip card conforming to ISO standards, being particular in that tonguing and grooving means (4-5) are established between the edges of the module (1) and the edges of the window (3) allowing said parts to be easily coupled to and uncoupled from each other, to be used jointly or separately, as required at each particular instance.
