PURPOSE: An apparatus for identifying the counterfeit of garbage bags with printed barcodes is provided to facilitate the identification of counterfeited garbage bags by providing duplication identifying signals based on barcode information. CONSTITUTION: A barcode reader(202) reads barcode information from barcodes printed on garbage bags. A first buffer(204) temporarily stores the barcode information. A second buffer(206) stores pre-read barcode information. If the barcode information of the first buffer and the second buffer is identical, a duplication identifying part(208) generates signals. The second buffer stores the barcode information based on a first-in-first-out method. |
