Abstract

Abstract 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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 127 words
- An intelligent card useful in telephony and thelike, essentially characterised by constituting the functional combination of two removably-mounted and preferably plastic independent parts, one part comprising the electronic identification module (1) and affording a format conforming to PrENV 1375-2 European pre-standard, and the other part comprising a laminar frame (2) having a window (3) capable of housing part (1) snugly, thereby together making up a chip card having a format in turn conforming to ISO 7810/13/16 standards, all in order that the electronic identification module (1) may be used on its own in subscriber identification modules conforming to the European pre-standard, whereas both parts (1) and (2) together make up a card that may be used in all other subscriber identification modules conforming to ISO standards.
Claim 2
Dependent Claim 127 words
- An intelligent card useful in telephony and thelike, essentially characterised by constituting the functional combination of two removably-mounted and preferably plastic independent parts, one part comprising the electronic identification module (1) and affording a format conforming to PrENV 1375-2 European pre-standard, and the other part comprising a laminar frame (2) having a window (3) capable of housing part (1) snugly, thereby together making up a chip card having a format in turn conforming to ISO 7810/13/16 standards, all in order that the electronic identification module (1) may be used on its own in subscriber identification modules conforming to the European pre-standard, whereas both parts (1) and (2) together make up a card that may be used in all other subscriber identification modules conforming to ISO standards.
Claim 3
Dependent Claim 69 words
- An intelligent card useful in telephony and the like, as in claim 1, characterised because part (1) comprising the electronic identification module has tongues or grooves (5) on its edges complementing grooves or tongues (4) respectively provided on the edges of the window (3) of the laminar frame (2), to define a stable coupling between both parts (1) and (2), easily removable by pressing inversely upon both parts.
Claim 4
Dependent Claim 51 words
- An intelligent card useful in telephony and the like, as in the above claims, characterised because parts (1) and (2) making it up are made of plastic materials of different strengths in order for one part, namely the part that is more costly to replace, to prevail over the other.
