# Filling in forms with barcodes

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 barcode and changes the barcode appearance.

Important: For any form with barcode fields, it’s essential that you fill it in on your computer. Don’t fill it in by hand on a printed copy. If you’re going to submit the form on paper, such as by mail or fax, be sure to fill it in electronically before you print it.

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.
