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.
