Claim 9:
10. A method to validate radio frequency identification (RFID) counts comprising:
affixing location tags with chips to be read through an area to be counted;
recording the location tags;
performing an RFID read of all items associated with each of the location tags, wherein the RFID read is associated with a most likely location tag, associating the RFID read with the most likely location tag further comprising:
ranking locations for each RFID tag by highest signal strength, highest average signal strength, and/or highest number of reads within a location's read timeframe;
calculating a combined score for each location and RFID combination; and
assigning the location with a highest combined score to each RFID tag;

comparing a piece count of all items associated with each of the location tags to the RFID read to identify whether the piece count matches the RFID read;
rejecting a location when the piece count does not match the RFID read; and
accepting a location when the piece count matches the RFID read.
