First Claim
Patent Images
1. An RFID system comprising:
- a sensor configured to detect a specific object; and
an RFID reader configured to read tag data from an RFID tag present in a communication area through radio communication according to detection of the object by the sensor, whereinthe RFID reader includes;
a specific-data storing unit configured to store tag data of a specific RFID tag; and
a control unit configured to transmit, when tag data coinciding with the tag data stored in the specific-data storing unit is not included in the tag data read from the RFID tag present in the communication area, the read tag data to a host apparatus.

Abstract
Tag data stored in a specific RFID tag is stored in a specific-data storing unit. Tag data is read from an RFID tag present in a communication area by an RFID reader through radio communication according to detection of a specific object by a sensor for detecting the object. When tag data same as the tag data stored in the specific-data storing unit is not included in the tag data read by the RFID reader, the read tag data is transmitted to a host apparatus.

9. An RFID tag reading method using a sensor configured to detect a specific object, an RFID reader configured to read tag data from an REID tag present in a communication area through radio communication, a read-data storing unit configured to store the tag data read by the RFID reader, and a specific-data storing unit configured to store specific tag data, the method comprising:
-
detecting the object with the sensor; reading the RFID tag present in the communication area with the RFID reader when the object is detected by the sensor; determining whether tag data same as the tag data stored in the specific-date storing unit is included in the tag data read by the RFID reader; and storing, when it is determined that tag data same as the tag data stored in the specific-data storing unit is not included in the tag data read by the RFID reader, the tag data read by the RFID reader in the read-data storing unit. - View Dependent Claims (10)
