Abstract
According to one or more embodiments, the tag reader includes a communication controller, a temperature measuring sensor, and a processor. The communication controller controls an output signal to be output from an antenna of the tag reader. The temperature measuring sensor measures an internal temperature of the tag reader. The processor sets the output value of an output signal based on the measured temperature and causes the communication control circuit to output the output signal from the antenna at the set output value.
