Although it is possible, the active type that uses a battery and operates a circuit for data communication using this as a power source has a problem that the battery consumption is very fast because the current in the standby state is large. is there.
In the case of the fourth sensor-equipped IC tag that is equipped with a memory for storing sensor measurement data, uses a contact-type switch, and communicates data by the switch operation, the measurement data even if the receiver is not within the communication distance Can be saved, and data can be viewed later, and even if it is an active type, battery consumption during reception can be kept low, but because it uses a contact switch, it can not be housing The environment to use was limited.
In this case, the setting of the IC tag and the request to the IC tag cannot be easily made unless the contact-type switch circuit is physically shut off.

JP 2000-227948 A (Patent Document 1) also includes an IC tag having a switching circuit for switching the supply of power from a power source. It only switches at every set time.
