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.

A wireless sensor device includes a flexible substrate, a cover layer on the flexible substrate, a device layer between the flexible substrate and the cover layer, and a printed circuit board connecting components of the device layer including an electrostatic discharge protected port for connecting an external sensor probe to the wireless sensor device. The device layer includes a processor, a memory, a battery, a first wireless communication system, and one or more onboard sensors; and a printed circuit board connecting components of the device layer comprising an electrostatic discharge protected port for connecting an external sensor probe to the wireless sensor device. The external probe allows for the wireless sensor device to perform sensor readings in environments that are too extreme or hostile to the wireless sensor device, while the wireless sensor device is safely isolated from the extreme or hostile environment.

An integrated circuit includes a voltage regulating circuit in the form of only one transistor, or a group of several transistors in parallel, that are connected between first and second terminals configured to be coupled to an antenna. A control circuit operates to make the voltage regulating circuit inactive when a pulse generated by an electrostatic discharge event appears at one of the first and second terminals, regardless of the direction of flow of the pulse between the first and second terminals. An electrostatic discharge circuit is further provided to address the electrostatic discharge event.

A coil antenna includes an insulator with a first principal surface and a second principal surface opposing to the first principal surface, a coil conductor provided on or in the insulator, a first pad electrode and a second pad electrode both provided on the first principal surface, and a third pad electrode and a fourth pad electrode both provided on the second principal surface. The coil conductor includes a first end and a second end. The first pad electrode and the third pad electrode are electrically connected to the first end side of the coil conductor, while the second pad electrode and the fourth pad electrode are electrically connected to the second end side of the coil conductor. Thus, the pad electrodes connected to the coil conductor are provided on each of the first principal surface and the second principal surface of the insulator.

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.

Provided is a data carrier comprising at least a first metallic layer, at least one electronic module, at least one antenna, and at least a second metallic layer. The second metallic layer is arranged after the first metallic layer with respect to an extension direction (E). The antenna is in connection with the electronic module. The first metallic layer is a continuous metallic layer delimiting a recess, and wherein the electronic module is at least partially arranged within said recess. Other embodiments disclosed.

An electronic module for a smartcard has a dual, contact and contactless, communication interface. The module includes an electrically insulating substrate on which are produced electrical contact pads enabling operation via contact with corresponding contacts of a smartcard reader, and contact pads for connection to corresponding pads of an antenna located on the body of the smartcard and enabling a contactless operation with a remote smartcard reader. The substrate is coated with a single electrically conductive layer, especially one made of metal, located on the lower face of the electronic module, and the upper face of the electronic module, which face is intended to be flush with the external face of the smartcard, is produced by said electrically insulating substrate, the latter being provided with windows leaving exposed all or some of said electrical contact pads.

A wireless sensor device includes a flexible substrate, a cover layer on the flexible substrate, a device layer between the flexible substrate and the cover layer, and a printed circuit board connecting components of the device layer including an electrostatic discharge protected port for connecting an external sensor probe to the wireless sensor device.

The external probe allows for the wireless sensor device to perform sensor readings in environments that are too extreme or hostile to the wireless sensor device, while the wireless sensor device is safely isolated from the extreme or hostile environment.

A metal card or a hybrid metal-plastic includes an acrylic resin protective clear-coat layer and/or a hard nano-particle top-coat layer overlying any exposed metal surface in order to insulate the metal and reduce the likelihood of an electrostatic discharge (ESD) or a short circuit condition. In a particular embodiment the hard nano-particle top-coat layer overlies the clear coat layer. The dual stage protective layers which include a clear-coat layer and a top-coat ensure that the problem associated with an ESD and/or a short circuit condition is minimized. In addition, the dual stage protection imparted to a card by forming a clear-coat layer and a top-coat layer ensures that any card surface treatment or card decoration is protected over time from excessive wear or scratching due to use in conjunction with a POS device and/or handling.
