RFID SYSTEM, COMMUNICATION DEVICE AND COMPUTER-READABLE MEDIUM
First Claim
1. A communication device configured to perform non-contact communication with an IC tag, the communication device comprising:
- a command receiver configured to receive a command from a control device configured to totally control reading/writing of information from/to the IC tag;
a first communication processing unit configured to perform communication with the IC tag in order to read/write tag information of the IC tag based on the command received by the command receiver;
an instruction output unit configured to output a communication instruction to another communication device in response to a first communication result obtained by the first communication processing unit; and
a response processing unit configured to generate response information to the control device based on the first communication result and a second communication result in said another communication device responsive to the communication instruction.

Abstract
An RFID system capable of freely installing a plurality of communication devices and designing a desirable communication area, and a communication device configured to implement the system. In the RFID system, a first communication device configured to communicate with a control device includes a command receiver configured to receive a command from the control device, a first communication processing unit configured to perform communication with an IC tag in order to read/write tag information of the IC tag based on the received command, an instruction output unit configured to output a communication instruction to another communication device in response to a first communication result obtained by the first communication processing unit, and a response processing unit configured to generate response information to the control device based on the first communication result and a second communication result obtained by a second communication device.

13. A non-transitory computer-readable medium storing computer executable instructions that when executed by a computer cause the computer to perform non-contact communication with an IC tag, the computer executing the steps of:
-
receiving a command from a control device configured to totally control reading/writing of information from/to the IC tag; performing communication with the IC tag in order to read/write tag information of the IC tag based on the received command; outputting a communication instruction to another communication device in response to a first communication result obtained by the communicating step; and generating response information to the control device based on the first communication result and a second communication result in said another communication device relative to the communication instruction.
