ABSTRACT:
A portable data carder assemblage includes smaller and larger plastic cards carrying respective embedded semiconductor chips for transferring data from the miniature card and standard-size card to, respectively, a small personal communicator cellular telephone set and a larger cellular set, the two cards being held in that assemblage by a pliant plastic sheath and a pocket on the sheath into which, respectively, the larger and smaller cards are inserted for safekeeping between uses of the cards. The assemblage may be conveniently transported by being lodged in a card-holding recess in the wallet of the owner of the assemblage. When that owner has only a personal communicator set, the standard-size chip carrying card is replaceable in the assemblage by a standard-size chipless card having therein an aperture into which the small card may be displaced by deformation of the sheath so that the assemblage takes up less room in the wallet.
