A free barcode generator is a website that allows users to create a barcode graphic by providing barcode data, encoding type and output file format. Users can use these barcodes for selling goods or linking others back to a website.
Users can also add barcodes to invoices and receipts or to packages for easy tracking. Barcodes can also be used to link someone directly to a photo, movie or letters. Some people use barcodes printed on paper and hidden around a city for a scavenger hunt. In stores, barcodes are on the sides of merchandise so consumers can use a scanner app on a phone to go to a product information page.
