1. A radio frequency identification (RFID) system, comprising:
- an RFID tag that sends a data tag information to an RFID reader;
at least one sensor that detects a location of a product associated with the RFID tag and transmits a location signal to the RFID reader; and
an aggregation component that receives the location signal and the corresponding data tag information from the RFID tag.

Abstract
System(s) and method(s) to increase the accuracy and efficiency of an RFID system is provided. A system includes an RFID tag that receives a signal from an RFID reader and an RFID tag that receives a signal from an RFID reader. The system further includes at least one sensor that detects the environment of a product associated with the RFID tag and transmits a environment detection signal to the RFID reader; and an aggregation component that receives the environment detection signal and a corresponding data tag information from the RFID tag. If a environment detection signal is not received, the RFID reader ignores the data tag information.
