A method of remote control is provided. A user interface of a controlling end inputs switching control signal. A first port of the controlling end transfers the control signal to a USB connector of an image capture unit. After being handled by a processor, the control signal is transferred to at least one controlled end through a second port by a USB-C connector of the image capture unit. Thus, the controlling end connects to and communicates with the controlled end, where the controlling end operates the controlled end with the user interface. Hence, the controlling end operates the controlled end with the connection of the image capture unit without switches and network. A simple method is obtained with cost effectively reduced.

The present disclosure provides a card tray, a card tray plug-in device, and a terminal. The card tray may include a first supporting portion and a second supporting portion connected with the first supporting portion. The first and the second supporting portions may both be configured for placing data cards, and configured on a same side of the card tray along a thickness direction of the card tray. The card tray may include an electrical connection portion, a data card supported on the first supporting portion and/or another data card supported on the second supporting portion may electrically connect with a card holder of a terminal through the electrical connection portion.

A modular transaction card assembly includes a card frame having the traditional dimensions of a credit card, and a transaction card that is smaller than a traditional card and that fits into a receptacle of the card frame. The card frame may include a window in which contact pads of the transaction card are positioned and flush with the surface of the card frame when the transaction card is secured in the receptacle. The card frame and transaction card assembled together may form a uniform assembly that appears and functions as a traditional transaction card (e.g., credit card).

A modular transaction card assembly includes a card frame having the traditional dimensions of a credit card, and a transaction card that is smaller than a traditional card and that fits into a receptacle of the card frame. Each of the card frame and the transaction card may be capable of performing contactless data transactions individually. The combined assembly of the card frame with the transaction card secured in the receptacle is also capable of performing contact data transactions, and in some instances, with an identifier that is distinct from the card frame or the transaction card alone. The card frame may include a processor enabling it to perform data encryption and authentication of the smaller transaction card.

The invention introduces an apparatus for accessing a memory card to at least include a host interface and a processing unit. The processing unit is arranged to operably inspect whether a logical block length utilized in a memory card inserted into a card reader can be supported by a host; and reply to the host with sense data that advises the host not to perform a subsequent write into the memory card through the host interface in response to a request sense command when the logical block length utilized in the memory card cannot be supported by the host.

A smartcard unit includes at least a smartcard and an attachment enabling the smartcard unit to be worn by a user. The smartcard is accessible to an external reader. A reader unit interfaces with the smartcard to enable an external computer to communicate with the smartcard. The smartcard unit or the reader unit has structure to align the reader unit relative to the smartcard unit in an alignment for communicative interfacing while the smartcard unit is being worn. The smartcard unit or the reader unit has a retainer to secure the reader unit in alignment relative to the smartcard so that the smartcard unit is reversibly separable from the reader unit without damage, in response to a force less than is necessary to detach or damage another part of said system, other than along a longitudinal axis of the smartcard or of a pair of components being separated.

In various embodiments, a chip card module is provided. The chip card module includes a chip card module contact array having six contact pads that are arranged in two rows having three contact pads each in accordance with ISO 7816, and three additional contact pads that are arranged between the two rows. Each additional contact pad is electrically conductively connected to a respective associated contact pad from a row from the two rows.

An IC card includes a communication unit and a controller. The communication unit can communicate with one communication destination by a plurality of interfaces including a first interface and a second interface. The controller processes a command received by the communication unit, and makes the communication unit transmit a response to the command. In a case where the first interface becomes unavailable after the communication unit receives the command by the first interface until the communication unit transmits the response to the command, the controller makes the communication unit transmit a response containing discontinuation information indicating that the transmission of the response to the command received by the first interface is discontinued by the second interface.

When an IC card is passed over an external card reading and writing apparatus, the IC card starts communication with the card reading and writing apparatus via a wireless interface, so that a change in the internal state of the IC card is reported to an external device via an external wired interface or a dedicated control signal line, thus allowing a specific application to be enabled on the external device or allowing a controller to be powered on and activated. Alternatively, the controller is powered off and deactivated. Accordingly, processing according to the communication state between the IC card and the card reading and writing apparatus or the internal state of the IC card can be smoothly initiated.

Provided is an information processing apparatus including an access control unit configured to control access from an application to a common file system accessible from a plurality of applications. The access control unit in a case where contact communication is performed with respect to an external processor, controls access by using first identification information for specifying an application, the first identification information being associated with each of the plurality of applications, and in a case where contactless communication is performed via a contactless communication device capable of performing contactless communication with an external device, controls access by using second identification information for specifying an application related to contactless communication, the second identification information being associated with at least one application among the plurality of applications.
