Some embodiments include a smart card reader system that includes a card reader cavity that is impervious to liquid. The card reader cavity includes a secure card reader (SCR) holder bonded to a printed circuit board (PCB), to provide a liquid barrier between the SCR holder and the PCB. The PCB includes an SCR spring contact connector. The card reader cavity can receive a smart card including an integrated circuit (IC), where the IC is coupled to the SCR spring contact connector. A processor coupled to the SCR spring contact connector, can receive an input regarding a transaction using data of the smart card, and execute the transaction. In some embodiments a roller system seals the card reader cavity when the smart card reader system is not in use.

In a card reader (1), if a shutter member (10), being located at a block position for blocking a card transfer path (3), rotates toward a deep side of the card reader, the shutter member moves to an open position. In a part within a surface of a side of the card transfer path in a thickness direction of the card (2), at a side deeper than the shutter member, there are formed only an open part (31) and an open part (32); the open part being for preventing an interference of the shutter member, rotating toward the open position, with the main body frame (4), as well as ejecting a foreign object out of the card transfer path; the open part being for preventing an interference of a movable component (21), placed so as to face the card transfer path, with the main body frame.

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 reader for interchanging data with a chip card includes a card insertion opening, a contact-making unit for interchanging data with a chip card which is inserted into the card reader through the card insertion opening, and a protective hood which covers the contact-making unit except for the card insertion opening. The protective hood is formed from two sheet-metal hoods which are stacked one in the other and an anti-drilling foil which is arranged between the said sheet-metal hoods and has an area-covering anti-drilling conductor track structure. The two sheet-metal hoods and the anti-drilling foil are adhesively bonded to one another over their full surface area to form a composite cover.

A card reader for use with a card having a magnetic stripe may include a card insertion port; a card passage through which the card inserted from the card insertion port passes, the card passage being connected to the card insertion port; a magnetic head configured to perform at least one of: recording magnetic data to the magnetic stripe of the card and reading magnetic data from the magnetic stripe of the card; a capacitive sensor provided in contact with the card passage; and a movable structure structured such that a distance to the capacitive sensor is variable. The capacitive sensor may include a plurality of regions, each of the plurality of regions being structured to detect a capacitance, and a switch circuit configured to electrically connect and disconnect each region of the plurality of regions.

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 capacitive sensor is divided into a plurality of regions each of which is capable of detecting a capacitance, and a switch circuit is provided which is configured to electrically connect and disconnect each region. At least one of the plurality of regions, for example, is arranged in a position less susceptible to an influence of a movable structure within the card reader, and at least one of the remaining regions is arranged in a position susceptible to the influence of the movable structure.

A hybrid transaction card reader system includes a hybrid transaction card reader and a device for protecting the hybrid reader. The hybrid transaction card reader includes a magnetic strip reader and a chip reader. The device for protecting the hybrid reader includes an upper protective printed circuit and a lower protective printed circuit. The hybrid reader further includes a lateral protective printed circuit which includes a superposition of unitary printed circuits, the plane of superposition of the unitary printed circuits being parallel to the plane of the upper protective printed circuit and to the plane of the lower protective printed circuit.
