Abstract
An interference suppression apparatus suppresses electromagnetic field interference produced by an RFID tag. The interference suppression apparatus includes a power supply circuit, an antenna that is connected to the power supply circuit, a clock that is connected to the power supply circuit, and a load adjuster that is connected to the power supply circuit. The clock generates an output in which a time constant is adjusted to be longer than a communication time of the RFID tag. The load adjuster changes a characteristic of the antenna based on the output from the clock.
