Communication device and communication method
First Claim
1. A communication device including a radio frequency identification tag that performs a radio communication with a predetermined device, the communication device comprising:
- a first metal body having an electrical conductivity; and
a space adjustment unit configured to adjust a space between the first metal body and the radio frequency identification tag, wherein the first metal body is configured to be replaced with a second metal body, and when the first metal body is replaced with the second metal body, the space adjustment unit is configured to adjust a space between the second metal body and the radio frequency identification tag;
wherein the space adjustment unit disables a communication function of the radio frequency identification tag by bringing the radio frequency identification tag into contact with the first metal body.
