摘要

An RFID reading system includes at least two readers and at least one RF tag. Each reader includes a transmitter, a receiver, and a CPU section to control transmission of the transmitter and reception of the receiver. Both readers receive a reply signal sent from an RF tag in response to a query wave sent from either one of the readers to the RF tag. The readers obtain tag information from the RF tag based on the received signals. To prevent interference therebetween, when one of the readers sends a query wave, transmission of a query wave from the other one thereof is stopped for a predetermined period of time. The information can be read without causing interference between the readers. There are obtained an RFID reading system, an RFID reading method, and RFID reader and a control program thereof, an RFID read control device and a control program thereof, and a computer-readable information recording medium storing the control programs.
