IC tag module, electronic device, information communication system, and communication control method for an IC tag module
First Claim
1. An IC tag module, comprising:
- a wireless port through which the IC tag module is adapted to send and receive data and to receive power wirelessly;
a wired port including a wired communication port through which the IC tag module is adapted to send and receive data and a wired power supply port through which the IC tag module is adapted to receive power;
a power supply circuit configured to combine power received through the wireless port and the wired power supply port and to supply power to the IC tag module, the power supply circuit being further configured to detect whether power is first supplied through the wireless port or the wired port;
a data storage medium configured to store data received through the wireless port and wired communication port; and
a control circuit configured to control the IC tag module, wherein the control circuit enables communication between the data storage medium and whichever of either the wireless port or the wired port through which power was first supplied, if power is supplied through both the wireless port and the wired port, and disables communication through the other port.

Abstract
An IC tag module enables data communication with, and receipt of power from, an external unit through a wireless port and enables the same with an electronic device in which the IC tag module is incorporated through a wired port, which includes a wired communication port and a wired power supply port. The IC tag module further includes a power supply circuit unit for combining power supplied from both the wireless port and the wired power supply port and for supplying the combined power supply to the IC tag module. A data storage circuit unit of the IC tag module stores data received through the communication ports, and a control circuit controls the operation of the module. The power supply circuit detects whether power is supplied first through the wireless port or the wired power supply port. If power is supplied from both ports, the control circuit enables communication with the data storage circuit unit through the port from which power was supplied first, and disables communication through the other port.
