Systems and methods allow for the integrated circuit cards (ICCs) to removably couple to each other and transmit information to an access device as a single device. One among the two or more ICCs coupled together may read data from the remaining ICCs and provide the data to an access device via contactless communication. The ICC may include a substrate; an integrated circuit embedded in the substrate; input ports exposed on a first surface of the substrate, and output ports exposed on a second surface of the substrate. The input ports and the output ports are electrically coupled to the integrated circuit. The output ports are configured to be removably coupled to the input ports of a second ICC.

The present application discloses a wearable apparatus having an apparatus main body including at least one receptacle for detachably attaching a smartcard. The wearable apparatus is compatible with a plurality of smartcards.

According to one embodiment, a microcontroller includes a processor, and a signal path that allows a signal conforming to an ISO7816 standard to be transferred between a card reader and a secure element without intervention of the processor.

An electronic device capable of accessing a memory card is provided. The electronic device includes a circuit board, a processing unit, a memory card slot, and a memory card access module. The processing unit is disposed on the circuit board. The memory card slot is disposed on the circuit board, allows the insertion of the memory card, and is coupled to the processing unit through a first signal line. The memory card access module is disposed on the circuit board for accessing the memory card. The memory card access module is coupled to the processing unit through a second signal line and coupled to the memory card slot through a third signal line and a fourth signal line. The first signal line, the second signal line, and the third signal line conform to the standard of a signal transmission interface.

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.

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 connector, a card holder, and a terminal device, where the card connector includes a plurality of first terminals and one or more second terminals. The first terminals are arranged to form a first card access area that installs a first card, and the first terminals are configured to be electrically coupled to the first card. The one or more second terminals are distributed on a periphery of the first card access area, the first terminals and the one or more second terminals form a second card access area that installs a second card, and the first terminals and the one or more second terminals are configured to be electrically coupled to the second card.
