Document Type and Number:
Japanese Patent JP7322439
Kind Code:
B2
Abstract:
To prevent unauthorized access to an IC module by non-contact IC card communication.SOLUTION: An IC card includes an antenna coil, a main IC module, a fingerprint sensor, and a fingerprint authentication IC chip. The fingerprint authentication IC chip includes a communication unit, fingerprint data storage means, and fingerprint collation means, and connects the antenna coil to the communication unit. The communication unit includes means for accumulating power received by the antenna coil in a power supply circuit and means for replying to a command of an external device received from the antenna coil. When the fingerprint collation means authenticates fingerprint data of a user, the power supply circuit is connected to the main IC module, so the main IC module is operated. The communication unit mediates communication between the main IC module and the external device.SELECTED DRAWING: Figure 2
