Abstract
According to one embodiment, an IC card includes an IC module and a substrate. The IC module includes a plurality of communication units, a storage unit, and a controller. The storage unit stores first data, and stores an access condition for the first data. The controller permits, when the access condition includes information which permits an access to the first data based on a reception command received via a first communication unit of the plurality of communication units, an access to the first data based on a first command received via the first communication unit, and does not permits an access to the first data based on a second command received via a second communication unit of the plurality of communication units.
Claims11
An IC card comprising:
- an IC module;
- and
- a substrate,
- the IC module comprising:
- a plurality of communication units;
- a storage unit configured to store first data, and to store an access condition for the first data;
- and
- a controller configured to permit, when the access condition includes information which permits an access to the first data based on a reception command received via a first communication unit of the plurality of communication units, an access to the first data based on a first command received via the first communication unit, and not to permit an access to the first data based on a second command received via a second communication unit of the plurality of communication units.
An IC card comprising:
- an IC module;
- and
- a substrate,
- the IC module comprising:
- a communication unit configured to transmit/receive data via a designated channel of a plurality of channels;
- a storage unit configured to store first data, and to store an access condition for the first data;
- and
- a controller configured to permit, when the access condition includes information which permits an access to the first data based on a reception command received via a first channel of the plurality of channels, an access to the first data based on a first command received via the first channel, and not to permit an access to the first data based on a second command received via a second channel of the plurality of channels.
An IC card manufacturing method comprising:
- manufacturing an IC card,
- wherein the IC card comprises:
- an IC module;
- and
- a substrate, and
- the IC module comprises:
- a plurality of communication units;
- a storage unit configured to store first data, and to store an access condition for the first data;
- and
- a controller configured to permit, when the access condition includes information which permits an access to the first data based on a reception command received via a first communication unit of the plurality of communication units, an access to the first data based on a first command received via the first communication unit, and not to permit an access to the first data based on a second command received via a second communication unit of the plurality of communication units.
An IC card issuing method comprising:
- storing issuance information in a storage unit of an IC card;
- and
- issuing the IC card,
- wherein the IC card comprises:
- an IC module;
- and
- a substrate, and
- the IC module comprises:
- a plurality of communication units;
- the storage unit configured to store first data, and to store an access condition for the first data;
- and
- a controller configured to permit, when the access condition includes information which permits an access to the first data based on a reception command received via a first communication unit of the plurality of communication units, an access to the first data based on a first command received via the first communication unit, and not to permit an access to the first data based on a second command received via a second communication unit of the plurality of communication units.
A communication method comprising:
- permitting, when an access condition for first data includes information which permits an access to the first data based on a reception command received via a first communication unit of a plurality of communication unit, an access to the first data based on a first command received via the first communication unit, and not permitting an access to the first data based on a second command received via a second communication unit of the plurality of communication units.
