TECHNICAL FIELD

The present disclosure relates to an RFID (Radio Frequency Identifier) tag and an RFID tag system that are capable of outputting information.

BACKGROUND ART

There has been proposed a technique of, in an RFID tag having a display, detecting failure of the display. (For example, see JP 2016-192179 A.) This RFID tag includes a photoelectric sensor that reads a detection pattern displayed on the display, and when the photoelectric sensor does not detect change in the detection pattern, a controller of the RFID tag determines that the display has a problem.

SUMMARY OF INVENTION

Solution to Problem

An RFID tag of the present disclosure includes:

an RFID device including a storage from and into which information is readable and writable from a reading/writing apparatus through wireless communication;

an output device that outputs information; and

a controller that reads information for output from the storage and controls the output device,

wherein the storage includes a first region into which the information for output is written and a second region separate from the first region, and

wherein the controller updates data of the second region in response to updating output of the output device.

An RFID tag system of the present disclosure includes:

The above-described RFID tag; and

the reading/writing apparatus,

wherein after writing the information for output into the storage, the reading/writing apparatus determines whether the data of the second region has been updated.

Advantageous Effects of Invention

According to the present disclosure, an advantageous effect that is as follows can be obtained: allowing a reading/writing apparatus to check completion of an output-information update process in an RFID tag having an information output function, without causing a rise in costs.
