Some forms include barcode fields, which capture and display other information in the form as a black-and-white pattern. You don’t have to do anything with the barcode area itself. As you fill in the form on your computer, the information you enter is included in the barcodes and changes the barcode appearance.
The barcode field makes collecting data easier for the form recipient because the barcode can simply be scanned. The results are an accurate and detailed summary of your input.
