Abstract
A reader apparatus includes a transmission circuit, a cancellation circuit, and a decoding circuit. The transmission circuit is configured to transmit a query wave that is obtained by modulating a carrier wave with a modulation signal representing a command to be transmitted to a first responder. The cancellation circuit is configured to cancel a modulation component corresponding to the modulation signal from a response wave transmitted using a backscattering method from a second responder different from the first responder. The decoding circuit is configured to decode data represented by the response wave from which the modulation component is canceled by the cancellation circuit.
