Barcode technology helps identify internal shrink between 0.5 and 1%. RFID on the other hand allows companies to see up to 70% shrink. Part of this benefit is realized due frequency of audits to the which are afforded by RFID. While most companies who use barcode perform annual or bi-annual due to the labor intensive process of performing these audits, companies who utilize RFID technology are able to perform nearly daily comprehensive audits which rectify inventories and ensure that shrink is known in real-time.
