First Claim
Patent Images
1. An apparatus for transmitting a sensor status of an RFID (radio frequency identification) tag, the apparatus comprising:
- one or more sensors sensing and measuring a physical change in an external environment;
a memory storing sensor data and sensor status information which are measured by the one or more sensors; and
a message generation unit generating a response message comprising an RFID tag ID (identifier), and at least one of a status record generated based on the sensor status information and the sensor data.

Abstract
Provided are a method and apparatus for transmitting a sensor status of a radio frequency identification (RFID) tag. The method and apparatus transmit an RFID tag identifier (ID) together with sensor data or sensor status information to an RFID reader, thereby enabling the RFID reader to receive the sensor status information about the RFID tag without additionally communicating with the RFID tag.
