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.

A card insertion part may include a base plate secured to a card reader main body; a substrate that is disposed on an opposite side of the card reader main body with respect to the base plate and including a light source installed on a surface thereof on an opposite side of the base plate; a cover with optical transparency that spreads over the substrate on an opposite side of the base plate; an insulating member that is disposed between the substrate and the base plate; and a flexible wiring member connected to the substrate. The substrate may include an opening through which the card is passed, and a ground wiring pattern formed on an area surrounding the opening. The ground wiring pattern may be electrically connected to the card reader main body via the flexible wiring member.

A card reader includes a contacting unit for exchanging data with a chip card and a plastic drilling protection cover which covers the contacting unit and has a plastic back-moulded conductor track foil which has an area-covering drilling protection conductor track structure. The drilling protection conductor track structure is applied, in particular printed, onto the conductor track foil using an electrically conductive, transparent ink.

A memory card reader body of a generally parallelepiped shape has a slot for insertion of a memory card and a housing to receive a memory card connector. The reader body has an upper cover and a lower base. The upper cover is made out of metal and the reader body further includes a printed-circuit board affixed to an upper face of the upper cover. The printed-circuit board includes at least one protection element.

A flexible printed circuit board may include a data signal circuit layer on which a data signal circuit is formed; and a destruction detection circuit layer on which a destruction detection circuit, structured to detect at least one of a break and a short-circuit of the destruction detection circuit layer, is formed, the destruction detection circuit layer overlapping the data signal circuit layer. The destruction detection circuit may be structured to carry destruction detection signals which are squarewave-shaped digital signals. The data signal circuit layer may include a first data signal circuit layer on which the data signal circuit is formed, the data signal circuit including linear-shaped first pattern wirings arranged parallel to one another. The destruction detection circuit may include a first destruction detection circuit layer including second pattern wirings formed by a linear portions orthogonally crossing the first pattern wirings and arcuate portions.

Systems, methods, and devices for concealed chip-card readers are disclosed. In one embodiment, a chip-enabled card reader may include a card slot that receives a chip-enabled card; a carriage comprising a smart chip connector for contacting a chip on the chip-enabled card; and at least one carriage track disposed within the chassis that slideably engages the carriage and defines a path of movement for the carriage between a protected position and a reading position. The carriage may move along the path of movement to a reading position. The smart chip connector may contact the chip on the chip-enabled card when the chip-enabled card is in a fully-inserted position. The carriage is in the protected position when no card has been inserted into the card slot. In one embodiment, the smart chip connector has reduced accessibility through the opening.

A memory card reader body includes proposed, on an internal face, a receiving recess to receive a memory card connector. The receiving recess has electrically conductive tracks forming a protective mesh for the memory card connector. The conductive tracks are such that they also extend on an external face of the memory card reader body through vias passing through the internal and external faces.

A multi-media reader (MMR) apparatus, secure transaction system and methods thereof are provided. The MMR apparatus includes a slot to receive a card and a near field communication (NFC) antenna to communicate with other NFC enabled devices and cards. The system is provided for securely sharing information over a network to complete one or more transactions using the MMR apparatus and a mobile device. The shared information may be separated and reassembled using on or more servers to increase security.
