Connector receptacles that can provide audible feedback to inform a user that a card has been properly inserted, and can include structures to protect contacts in a connector receptacle from damage due to an improper card insertion. An example can provide a connector receptacle having a click module to provide audible feedback indicating that a card has been fully inserted. Another example can provide a connector receptacle having movable contacts that can remain out of an insertion path until the card is at least partially inserted.

A card reader includes a card lock mechanism preventing pulling-out of a card jammed in a card conveyance passage, and an operation part for manually releasing lock of the card caused by the card lock mechanism. The card lock mechanism includes a motor, and a lock member which is provided with a blocking pawl for preventing pulling-out of the card and is moved between a contact position where the blocking pawl contacts the card and a retreated position where the blocking pawl is retreated from the card conveyance passage. The operation part includes a rotation member in a tube shape having an inner circumference wall surrounding an output shaft of the motor, and an engaging member provided on the inner circumference wall and extended along a circumferential direction of the output shaft and engageable with an outer peripheral face of the output shaft. The engaging member is elastically deformable.

A system for prevention of electrostatic discharge from a payment card to a point of sale (POS) device comprising an integrated circuit card (ICC) socket, includes a spring member comprising a first end electrically coupled to a second end. The first end is electrically coupled to an electrical ground, the first end is mechanically coupled to the POS device, and the second end is positioned for contact with a top edge of the payment card. When the payment card is inserted into the ICC socket and the top edge comes into contact with the second end, the first end and the second end form a first electrical path for electrostatic discharge between the payment card and the electrical ground.
