Embodiment approach 1

[0094] Hereinafter, an embodiment of one aspect of the present invention (hereinafter also referred to as "this embodiment") will be described based on the drawings.

Embodiment approach 2

[0125] Another embodiment of the present invention will be described below. In addition, for convenience of description, members having the same functions as those described in the above-described embodiments are denoted by the same reference numerals, and description thereof will not be repeated.

[0126] Figure 5 It is a block diagram showing a schematic configuration of the communication system 100 according to this embodiment. Such as Figure 5 As shown, the data processing unit 22 further includes a mode selection unit 33 . When the mode selection unit 33 reads data from the RFID tag 4, it selects the first mode (encryption mode) for instructing the RFID tag 4 to transmit encrypted data and instructing the RFID tag 4 to transmit unencrypted data. Either of the second mode (non-encrypted mode) of the data.

[0127] Switching to the second mode is performed when, for example, the two-dimensional code 41 of the RFID tag 4 cannot be read optically due to contamination or...

Embodiment approach 3

[0151] Another embodiment of the present invention will be described below. In addition, for convenience of description, members having the same functions as those described in the above-described embodiments are denoted by the same reference numerals, and description thereof will not be repeated.

[0152] (Outline of communication system)

[0153] Figure 9 It is a schematic diagram showing the outline of an example of the communication system of this embodiment. Such as Figure 9 As shown, the communication system includes a Wifi (registered trademark) router 150 and a notebook PC 110 as communication devices of communication objects. The notebook PC 110 includes a camera 111 (refer to Figure 11 ), the camera 111 photographs the two-dimensional code 120. The notebook PC 110 can communicate with the Wifi router 150 through Wifi communication.

[0154] Here, in this embodiment, the Wifi router 150 and the notebook PC 110 use the encryption key indicated by the two-dimen...

Abstract

The invention provides a communication device, a communication system, an RFID tag, and a method for controlling the communication device, which achieve secure communication with the RFID tag withoutcomplicating management. The reader / writer (2) is provided with: an optical reading unit (24) that optically reads an encrypted image from the RFID tag (4), the RFID tag (4) displaying the encrypted image indicating an encryption key on the surface of the RFID tag (4); and an RF communication unit (23) that wirelessly transmits or receives the data encrypted using the encryption key to or from theRFID tag (4).

Description

technical field [0001] The present invention relates to, for example, a reader / writer for wireless communication with a radio frequency identification (Radio Frequency Identification, RFID) tag, wireless fidelity (Wireless Fidelity, Wifi) (registered trademark) or Bluetooth (Bluetooth) (registered trademark) A communication device for communication, a communication system, an RFID tag, and a control method for the communication device. Background technique [0002] A wireless communication system using a reader / writer and a radio frequency identification (RFID) tag is known as prior art. Such a wireless communication system is used, for example, in the management of products in a factory. Here, when using a reader / writer with a long communication distance, for example, there is a concern that the information on the RFID tag may be read out from outside the factory.
