A smartcard having a security controller, a fingerprint sensor, and an energy supply circuit configured to supply the security controller and the fingerprint sensor with energy, wherein the security controller and the fingerprint sensor are configured to communicate with one another by means of inductive coupling.

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.

An RF tag has a particular structure of an RF tag antenna to which an IC chip is mounted. The RF tag antenna includes: an inductor pattern section having a C-shape and configured in a form of a flat plate; a notch section formed by cutting out a periphery of the inductor pattern section; an antenna section formed around the notch section; and a ground section provided in continuation with the inductor pattern section and configured in a form of a flat plate.

Embodiments of the present disclosure relate to a stabilizing apparatus for a plug-in card, a chassis including the stabilizing apparatus and associated manufacturing method. The stabilizing apparatus comprises a fixed part adapted for attaching the stabilizing apparatus to a chassis for supporting the plug-in card and a contact part electrically coupled to a ground terminal of the chassis and movable towards the plug-in card supported on the chassis along a first positive direction perpendicular to an extended plane of the plug-in card, so as to contact the plug-in card.

The present invention provides a contactlessly readable tag with which both a small tag size and long-distance readability can be achieved, a method for manufacturing the contactlessly readable tag, an identification device, and an identification information determination system. In this tag 200, the arrangement pattern of metal parts in a metal pattern layer 202 of this tag 200 is associated with identification information, and when irradiating the tag 200 with electromagnetic waves, the identification information can be read on the basis of the information of the electromagnetic waves reflected by the tag 200, and the metal pattern layer 202 is provided closer to a reading surface side of the tag 200 than a buffer layer 201 having at least a single layer.

Provided is a memory device. The memory device includes a module board on which one or more semiconductor devices are disposed and a conductive plate mounted on a first side of the module board. The conductive plate includes a shielding region and a non-shielding region. A pad is disposed in the shielding region of the conductive plate.
