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.

A gate assembly can include a housing, a main body, at least one member, and an activation rib. The housing can define at least a portion of a card path of a payment interface. The main body can be coupled to the housing and can be movable between a closed position and an open position. The at least one member can extend from the main body such that, when the main body is in the closed position, the at least one member extends into the card path and can be oriented to inhibit an item from traveling through the card path. The activation rib can extend from the main body and can be located such that, when the main body is in the closed position, the activation rib extends into the card path. Related apparatus, systems, techniques, and articles are also described.

A card reader may include card insertion port; a plurality of types of pulling-out detection mechanisms; and a pulling-out prevention mechanism. The pulling-out prevention mechanism may include a lock member having a prevention part configured to contact with the card and prevent pulling-out of the card; and a moving mechanism structured to move the lock member between a contact position and a retreated position. The plurality of types of the pulling-out detection mechanisms may the abnormal pulling-out of the card by methods different from each other. The lock member is moved to the contact position from the retreated position to prevent pulling-out of the card when the abnormal pulling-out of the card from the card insertion port is detected by the plurality of types of the pulling-out detection mechanisms.

A card reader may include a card passage where a card inserted into an insertion port for the card is passed, a shutter member for closing the card passage, a magnetic head disposed on a rear side relative to the shutter member and structured to perform reading of magnetic data recorded in a magnetic stripe of the card and/or recording of magnetic data to the magnetic stripe, and a foreign matter detection mechanism which is structured to detect a foreign matter attached to the card passage. The foreign matter detection mechanism is disposed on a rear side relative to the shutter member and is disposed at a position in the width direction of the card where the magnetic stripe is passed. The foreign matter detection mechanism may be structured of an electrostatic capacitance sensor.

A card reader may include a card conveying mechanism; a guide; a magnetic head; a positioning member to position the card relative to the magnetic head; and a shutter. The positioning member may include a card abutting part to abut a third direction end of the card; and a card support part to contact a first direction side of the card. A distance between the card abutting part and a third direction end of the guide is shorter than a width in the short-side direction of the card. When the shutter has closed, a fourth direction end of the shutter is disposed on a first direction side of the guide. When the shutter has opened the opening, the shutter is disposed on the first direction side of the guide. The third direction end of the card may be guided to the card support part by the shutter.

Various embodiments related to a card reader are described. According to an embodiment, the card reader comprises: a card reader body part; a contact card recognition module included in the card reader body part; a circuit board having a contactless card recognition module included in the card reader body part; a card insertion hole which is formed in the card reader body part and allows a contact card and a contactless card to be inserted; and a rotation guide part rotatably provided within the card insertion hole, wherein the rotation guide part may recognize the contact card in the contact card recognition module by passing the contact card through the card insertion hole according to a rotation, and may recognize the contactless card in the contactless card recognition module by limiting a movement according to a contact after inserting the contactless card into the card insertion hole. In addition, various other embodiments are possible.

A transaction card reading system, which includes: a transaction card reader having a slot for inserting a transaction card; and a protective flap movable between two positions: a closed position wherein the flap closes the insertion slot, and an open position wherein the flap is disposed at least partly outside the insertion slot. The protective flap includes a closure element integrally mounted on a one-piece support element, the closure element being shaped and dimensioned to close the insertion slot in the closed position. The one-piece support element includes at least one elastically deformable portion so as to allow switching from the closed position to the open position and vice versa.
