Abstract: A method for providing additional services by a UICC applied in a cellular phone is provided. First, an aperture would be formed on the UICC provided by a first service provider, and the UICC may include a first IC and first contact pads coupled to the first IC. This aperture could be formed by means of a puncher. After that, a laminated integrated circuit card would be attached to the UICC by a second service provider to form a dual UICC. Such laminated integrated circuit card may include a second IC and second contact pads coupled to the second IC, and the second IC is deposited in said aperture. Preferably, the size of the second IC or the shell protecting the second IC fits perfectly for the aperture, and the great reliability could therefore be ensured. Finally, the additional service is able to be provided based on the dual UICC via wireless transmission or reception of the cellular phone.

Abstract: A dual card system for a portable device and a fixed terminal machine is disclosed. The dual card system includes a first card having a first substrate and a first integrated circuit (IC) provided with a first plurality of contacts on a top surface of the first substrate, and a second card having a second substrate and a second IC provided with a second plurality of contacts on a top surface of the second substrate. The second substrate is provided with a first plurality of pins on a bottom surface thereof, to be electrically coupled with the first plurality of contacts, respectively.

Abstract: The present invention discloses the dual universal integrated circuit cards (UICC) system for a portable device, the portable device includes a cellular phone or a personal digital assistance. The system comprises a slayer integrated circuit (IC) card having a first integrated circuit (IC). A substrate is carrying for a master integrated circuit (IC) card having a second integrated circuit (IC) and a contact interface. The contact interface is coupled to the first and second integrated circuit (IC). An antenna is coupled to the second integrated circuit (IC) for transmitting information.
