Abstract
A tag reader includes a communication controller, a communication interface, and a processor. The communication controller controls an output level of an output signal to be output from an antenna for reading an RFID tag. The communication interface communicates with a host device. The processor specifies a minimum output level of the output signal at which the RFID tag can be read and transmits the minimum output level to the host device through the communication interface.
Claims20
A tag reader, comprising:
- a communication controller configured to control an output level of an output signal to be output from an antenna for reading a wireless tag;
- a communication interface configured to communicate with a host device, and
- a processor configured to specify a minimum output level of the output signal at which the wireless tag can be read and transmit the minimum output level to the host device through the communication interface.
A tag reader, comprising:
- an antenna;
- a communication control circuit connected to the antenna and configured to control an output level of an output signal output from the antenna for reading a wireless tag;
- and
- a processor connected to the communication control circuit and configured to:
- execute a plurality of reading attempts of the wireless tag using different output levels;
- determine a minimum output level for the output signal at which the wireless tag can be read in the plurality of reading attempts;
- and
- transmit the minimum output value to a host device along with tag information read from the wireless tag.
