摘要:
A shield element for mounting on an object, in particular a flat object, such as a chip card. The object has a base body, an RFID or NFC transponder, a transponder chip and a coil-shaped transmission antenna connected to the RFID or NFC transponder chip. The shield element has a carrier made of non-conductive material. The carrier has a closed or closable conducting path which, upon mounting the shield element on the object, shields the object from the electromagnetic fields generated by an external reading device and directed at the transmission antenna of the RFID or NFC transponder chip.

An apparatus and method is provided to shield contactless portable electronic consumer devices such as radio frequency identification devices (RFID), tokens, mini-cards, key fobs, cellular phones, smartcards, etc. from wireless interrogation. In one embodiment, a contactless portable consumer device which includes a first antenna is shielded from unauthorized wireless interrogation with a radio frequency (RF) shield. The RF shield includes electrically conductive, non-ferromagnetic material and is configured to prevent unauthorized data transfer between a second antenna external to the portable consumer device and the first antenna.

A low profile USB flash memory device, and methods of forming same, are disclosed. The USB flash memory device includes an integrated circuit memory portion and a USB connector. The memory portion and the USB connector may be integrally formed on the same substrate. The USB flash memory device includes a substrate on which is mounted one or more flash memory die, a controller die, passive components and an LED for indicating when the memory is being accessed. In contrast to prior art USB memory devices which used TSOP packages mounted on a printed circuit board, the semiconductor die of the present invention are affixed to the substrate and wire bonded in a SIP configuration. Omitting the encapsulated TSOP packages allows a reduction in the overall thickness of the USB flash memory device.

A laminated core stock sheet for use in a composite laminate assembly configured for being separated into plural individual cards is provided. The laminated core stock sheet includes a core substrate layer and an intermediate filmic layer coupled to the core substrate layer. The intermediate filmic layer includes plural conductive bodies spaced apart from each other that provide at least one of a security feature, a decorative feature, or other functional feature of the individual cards. The core substrate layer and the intermediate filmic layer are configured to be coupled with another laminated core stock sheet that may or may not include the intermediate filmic layer to form the composite laminate assembly configured for being separated into the individual cards.
摘要:
A semiconductor device capable of wireless communication, which has high reliability in terms of resistance to external force, in particular, pressing force and can prevent electrostatic discharge in an integrated circuit without preventing reception of an electric wave. The semiconductor device includes an on-chip antenna connected to the integrated circuit and a booster antenna which transmits a signal or power included in a received electric wave to the on-chip antenna without contact. In the semiconductor device, the integrated circuit and the on-chip antenna are interposed between a pair of structure bodies formed by impregnating a fiber body with a resin. One of the structure bodies is provided between the on-chip antenna and the booster antenna. A conductive film having a surface resistance value of approximately 106 to 1014 Ω/cm2 is formed on at least one surface of each structure body.

摘要:
A contactless communication medium which can prevent invasion of static electricity and has an outer surface which can satisfy requirements on the flatness thereof. The contactless communication medium has a sealing member including an insulating layer and a conductive layer provided in a stacked manner and having a shape covering an IC module is located such that the insulating layer is on the IC module side. Owing to this, static electricity coming from outside is diffused by the conductive layer and blocked by the insulating layer. Thus, adverse influence of the static electricity on the IC module is prevented. The contactless communication medium can also satisfy the requirements on the flatness of an outer surface thereof.
