A biometric smart card includes a first polymer layer, an electrical substrate layer having at least one interconnect layer over the first polymer layer, an antenna proximate to the electrical substrate layer, a metal layer proximate to the antenna and the electrical substrate layer, the metal layer comprising a plurality of circumferential apertures, and a second polymer layer over the metal layer, wherein the plurality of apertures in the metal layer allow the smart card to flex in one, two or three dimensions.

Biometric smart card having an apertured metal layer

A smart card inlay comprising an inductive antenna, and a capacitive network. The inductive antenna is configured to (i) communicate wirelessly with a card terminal, and (ii) power the card circuitry via inductive coupling to the card terminal. The capacitive network is connected in parallel with the inductive antenna. The capacitive network comprises a first capacitor in series with a second capacitor. The second capacitor is connectable in parallel with card circuitry. The first capacitor has a capacitance Cand the second capacitor has a capacitance C, the ratio C/Cbeing so as to match the impedance of the card terminal as reduced by the capacitive network to the impedance of the card circuitry.

Load matching in a smart card

A device for contactless communication with a terminal, the device comprising: an antenna for receiving a wireless signal emitted by the terminal; an embedded chip configured to generate data for communication to the terminal to perform a first function associated with the device; and a module separate from the chip configured to perform processes as part of a second function associated with the device, the module being connected to the antenna and comprising a power-harvesting unit configured to harvest power from the received wireless signal to power at least the module.

Device architecture

Devices, systems, and methods facilitate enrollment of authenticating biometric data for authenticating an authorized user via a biometric sensor. A data input device and a power source are operatively coupled to a smart card including a fingerprint sensor. An activation code input by the user interacting with the data input device is compared with a predefined activation code, and if the detected activation code matches the predefined activation code, a fingerprint template is enrolled from fingerprint data received from the fingerprint sensor, all without transmitting data from either the power source or the data input device to any device other than the smart card.

Secure, remote biometric enrollment

A novel sensor is provided having a plurality of substantially parallel drive lines configured to transmit a signal into a surface of a proximally located object and also a plurality of substantially parallel pickup lines oriented proximate the drive lines and electrically separated from the drive lines to form intrinsic electrode pairs that are impedance sensitive at each of the drive and pickup proximal locations. A switch is integrated with the sensor.

Biometric image sensing

A biometric module implemented on a single integrated circuit chip is configured to perform processing as part of a function associated with a device that performs contactless communication with a terminal. The module comprises a power-harvesting unit to induce a voltage from a wireless signal received at an antenna of the device; one or more components configured to process functions in the digital domain; one or more components configured to process functions in the analogue domain; and first and second voltage regulators each having inputs for receiving an input voltage induced by the power-harvesting unit. The first voltage regulator outputs a first voltage to the components processing functions in the analogue domain and the second voltage regulator outputs a second voltage lower than the first voltage to the components processing functions in the digital domain.

Voltage regulation

A sensor has drive lines and transverse pickup lines to define an electrode pair where each pickup line crosses a drive line. A reference pickup line is arranged parallel to the pickup lines and a compensation drive line is arranged parallel to the drive lines. A signal source provides a first signal to the drive lines and a second signal that is the inverse of the first signal to the compensation drive line. An amplifier has a first input connected to a pickup line, a second input connected to a reference pickup line, and a output indicative of an object in contact with the electrode pair(s). Each impedance between the compensation drive line and a pickup line, between the reference pickup line and a reference drive line, and between the compensation drive line and the reference pickup line is equal to the impedance at the electrode pair when no object is contact with the electrode pair.

Fingerprint sensor employing an integrated noise rejection structure

A sensor assembly comprises a rigid substrate with a circuit subassembly wrapped therearound. The circuit subassembly includes a flexible substrate with conductive traces and interconnects formed thereon, and when wrapped around the rigid substrate, the conductive traces may overlap one another so as to form capacitive sensor elements. The interconnects connect the conductive traces to one or more components, such as a printed circuit board attached to a portion of the flexible substrate. The sensor assembly maybe installed in an opening formed in a host device panel of a host device, such as a smart phone, with the sensor assembly optionally peripherally surrounded by a spacer frame, and covered by a cover element. The circuit subassembly may include a host connector tab for electrically connecting the sensor assembly to electrical components of a host device.

Devices, systems, and methods facilitate enrollment of authenticating biometric data for authenticating an authorized user via a biometric sensor. In one aspect, power is transmitted to a smart card from a power source removably coupled to the smart card, the power source including a power element that provides power to the fingerprint sensor and a finger guide comprising two or more finger guide channels positioned adjacent to the fingerprint sensor of the smart card when the power source is coupled to the smart card. Each finger guide channel is configured to position a finger placed thereon to contact the fingerprint sensor at a different orientation. During the transmission of power to the smart card, the user is instructed with respect to the placement and removal of the user's finger with respect to each finger guide channel with a status indicator associated with the finger guide channel.

Power source for biometric enrollment with status indicators

Devices, systems, and methods facilitate enrollment of authenticating biometric data for authenticating an authorized user via a biometric sensor. Included devices transmit power to a sensor-enabled device that does not have an independent power source without transmitting data to or from the device. Data input devices coupled to the biometric sensor enable user input of non-biometric data, such as an activation code, via the biometric sensor. For biometric sensors comprising fingerprint sensors, finger guides position a finger to contact the sensor at a desired orientation. Systems and methods allow for enrollment of one or more authenticating biometric data templates with or without requiring input of non-biometric authentication data, such as an activation code.

Device and method to facilitate enrollment of a biometric template

A sensor assembly includes a flexible substrate with conductive traces formed on opposed sides of the substrate and oriented transversely to each other. The substrate is wrapped around a core so that the traces formed on opposed sides of a first part of the substrate form a first sensor surface on one surface of the core, and the traces formed on opposed sides of a second part of the substrate form a second sensor surface on an opposed surface of the core. The core may comprise an encapsulant overmolded onto the conductive traces on a surface of the first part of the substrate, and the second part of the substrate is folded over the encapsulant. The sensor assembly may include an integrated circuit disposed on the flexible substrate, wherein one or more of the conductive traces are electrically connected to each integrated circuit.

A fingerprint sensor module includes a fingerprint sensor assembly with a circuit element attached. The fingerprint sensor assembly is electrically connected to a printed circuit board (PCB) substrate with a cutout to accommodate the circuit element. The entire fingerprint sensor assembly and at least part of the PCB are encapsulated in a encapsulating material to produce a structurally robust fingerprint sensor module suitable for integration into an electronics device such as a smartphone or other 'Internet of Things' (IOT) electronic device.
