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.

The application provides an enrolment card for a biometric card with a first card body. The enrolment card includes a battery for providing electrical power, a microcontroller unit that is electrically connected to the battery, and a plurality of contact pins that are electrically connected to the battery and to the microcontroller unit. The enrolment card further includes a second card body with a card engagement element. The second card body is sized to correspond to the first card body. The battery and the second microcontroller unit are embedded in the second card body. The enrolment card provides an enrolment mode, wherein the card engagement element engages with the first card body for allowing the contact pins to contact corresponding contact pads of the biometric card and the battery provides the electrical power to the biometric card.

A memory card includes an upper case, a lower case, and an integrated circuit package between the upper case and the lower case. The integrated circuit package includes a memory stacked chip on a panel substrate, and the memory stacked chip includes a base memory stacked chip and an additional memory stacked chip stacked on the base memory stacked chip. The integrated circuit package includes a frequency boosting interface chip on the panel substrate and electrically connected to the memory stacked chip, and a controller chip on the panel substrate and electrically connected to the memory stacked chip and the frequency boosting interface chip.

A cardholder sleeve and a computing device paired with the cardholder sleeve configured to operate as near-field communication (NFC) proxy devices for one or more integrated circuit (IC) chip cards held in the cardholder sleeve is disclosed. The cardholder sleeve includes at least one pocket to hold an IC chip card and at least one internal card reader adjacent to each pocket, and is configured to wirelessly pair with the computing device via a wireless communication protocol. When the computing device comes in close proximity to an external card reader, the NFC interrogation occurs with the computing device acting as a proxy for the card held in the cardholder sleeve. In this way, the cardholder sleeve and computing device form a repeater network that enables the card to be interrogated remotely on a per-transaction basis.
