The program calculates the check digit of the EAN-13 barcode. You need to enter 12 digits of the barcode and the program will calculate and display the 13th digit (which is the check digit). This app is also a free EAN-13 barcode generator (aka barcode creator). The program will be useful for you if you need to create a standards-compliant EAN-13 barcode. The generated barcode is suitable for printing on product packages or labels. You can share the generated barcode as a high-quality PNG format file. The barcode is displayed large on the device screen, so you can scan directly from the screen. Generate a barcode for retail item numbering.
