A system includes: a physical wallet configured to attach to a first mobile communication device and to physically store a first funding card and additional funding cards in a holding compartment; a non-transitory memory; and one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising: associating a plurality of funding cards with the first mobile communication device, wherein the first funding card is not a member of the plurality of funding cards associated with the first mobile communication device; and detecting when the first funding card is physically removed from the holding compartment of the system; and transmitting a notification to a computer in response to the first funding card being physically removed from the holding compartment.

An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

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).

An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

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.

The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

Disclosed is an electronic device, which is connection device fastenable to a portable electronic device, comprising: a fastening part fastened to a USIM connector of the portable electronic device; a circuit board extending from the fastening part and connected to a plurality of connectors; a processor implemented on the circuit hoard; and a switching circuit unit, wherein the processor is set to supply power to an external device selected, through the switching circuit unit, from among at least one external device connected to the plurality of connectors or to transmit to and receive data from the selected external device. Additionally, various examples identified through the description are possible.

An access control system that utilizes a combination of passive tags and active RFIDs. The system may combine passive and active circuitry in one package or may be separable. The system may incorporate legacy passive access control tags. An access control tag may be associated with a network protocol ID.

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.

A temporary carrier of a removable memory card (2) is in the shape of a flat card (1), where the removable memory card (2) forms an element to be released from the flat card body (1). The removable memory card (2) has at least five additional contacts (4) for temporary usage before the removable memory card is removed from the flat card (1) body. The additional contacts (4) take up a smaller surface as a contact field (5) of a standardized flat card (1). The removable memory card (2) is located within the flat card (1) in such a way that the position of additional contacts (4) corresponds to the position of a standardized flat card (1) contact field (5). The suitable sixth additional switch contact (8) can be used to switch secure elements. The temporary carrier is inserted into a standard burning device, which operates with it in the same way as it would with a common card with a contact field (5).
