Barcode scanners are the most accurate way of retrieving product information from a barcode. Smartphones can have barcode scanning apps downloaded onto them which allow you to scan a UPC or EAN-13 barcode and get results from the internet from sites such as BarcodesDatabase.org, ibnverified.org, Amazon.com, UPCdatabase.org and various others. There are multiple apps available for download. A popular choice is Zebra Barcode Scanner app – this app seems to have the highest chance of returning the product information of any barcode that you scan.
