1. An IC tag, comprising:
- a receiving unit receiving a command of a first communication protocol and a command of a second communication protocol; and
a control circuit switching a first operational mode to a second operational mode when the IC tag receives a specific command of the first communication protocol and switching the second operational mode to the first operational mode when the IC tag receives a specific command of the second communication protocol, wherein the IC tag operates based on the first communication protocol in the first operational mode and the IC tag operates based on the second communication protocol in the second operational mode.

Abstract
By canceling the invalidation, there is provided an IC tag that can be reused after the IC tag'"'"'s function was invalidated. An IC tag according to an embodiment operates in accordance with a standard protocol and a non-standard protocol and includes a control circuit for switching an operational mode, when receiving a KILL command during an operation based on the standard protocol, to an invalidated state based on the non-standard protocol, and when receiving a KILL cancel command during an operation based on the non-standard protocol, to a normal state based on the standard protocol.

17. An IC tag system, comprising:
-
an IC tag that operates in accordance with a first communication protocol and a second communication protocol; and
a reader/writer communicating with the IC tag, the IC tag comprising;
a receiving unit receiving a command of a first communication protocol and a command of a second communication protocol; and
a control circuit switching a first operational mode to a second operational mode when the IC tag receives a specific command of the first communication protocol and switching the second operational mode to the first operational mode when the IC tag receives a specific command of the second operational protocol, wherein the IC tag operates based on the first communication protocol in the first operational mode and the IC tag operates based on the second communication protocol in the second operational mode.
