A card reader for data exchange uses a chip card inserted into a card reader housing up to a data exchange position having an electrical contact arranged fixedly in the card reader housing or displaceably in the card insertion direction. In the data exchange position, projecting into the card path of the inserted chip card by way of a contact area, includes a detector device. In the case of a contact fixedly arranged in the card reader housing, the detector device is directed at the contact face of the contact or at the region around said contact face or which, in the case of a contact that is displaceably arranged in the card reader housing in the card insertion direction, is directed at the position in the card reader at which the contact face is located in the data exchange position, or is directed at the region around this position.

A card edge connector with members configured to secure a mating component so as to improve the connector’s reliability. The connector housing may have a slot configured to receive the mating component. The slot has a first portion configured to receive a front edge of the mating component, and second portions extending from opposite ends of the first portion and configured to receive side edges of the mating component. Members are disposed in the housing and have beams curving into respective second portions of the slot. The beams of the members are configured to restrain movement of the mating component when the mating component is inserted into the slot. Such a configuration enables more reliable connections and improves the connector’s shock resistance while being compatible with mating components having a variety of sizes.

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 SIM card connector includes an insulating body, a plurality of first terminals and a plurality of second terminals. The insulating body has a plurality of first slots and a plurality of second slots. Each side wall of each first slot has a limiting slot. The plurality of the first terminals are inserted into the plurality of the first slots. Each first terminal has a first base portion, a first soldering portion connected with a lower end of the first base portion, and a first contacting portion connected with an upper end of the first base portion. The plurality of the second terminals are inserted into the plurality of the second slots. Each second terminal has a second contacting portion slantwise extended towards a rear end of the insulating body and exposed beyond a top surface of the insulating body.

A card connector is provided for receiving an inserted card module. The card connector includes a housing including a terminal holding portion for arranging terminals to make contact with electrode pads on the card module. Each terminal includes a base portion held by the terminal holding portion and a cantilevered arm portion extending from the base portion in an inclined direction relative to the transverse direction of the housing. Each arm portion includes a curved portion and a pair of inclined portions. The curved portion has a curved profile with a curved surface positioned so the center of curvature is positioned above. The inclined portions are inclined relative to the extension direction of the arm portion on both sides of the apex portion positioned at the free end. The inclined portions each have a different angle of inclination relative to the extension direction of the arm portion.

A card connector includes a transmission conductor assembly. The transmission conductor assembly includes a first signal transmission conductor, a first power transmission conductor, an inspection signal transmission conductor, a second signal transmission conductor, a command reset transmission conductor, a first grounding transmission conductor, a second power transmission conductor, a first differential transmission conductor, a second differential transmission conductor, a third signal transmission conductor, a second grounding transmission conductor, a third grounding transmission conductor, a third differential transmission conductor, a fourth differential transmission conductor, a fourth grounding transmission conductor, a fifth grounding transmission conductor, a fifth differential transmission conductor, a sixth differential transmission conductor, and an outside grounding transmission conductor, each of which has a spring section and a soldering section. The soldering sections, being so arranged, achieve advantages of bettering high frequency performance, reducing capacitive effect, and suppressing electromagnetic radiation interference.

To provide a card reader that encrypts information acquired via an IC contact block.
