# Scan Barcodes as Input

In some cases, the information contained in a barcode symbol is exactly what is needed to fill a form. For example, you can scan the Universal Product Code (UPC or UPC Code) on a product to search for it in an online store, or you can scan the barcode on a courier package to see where it has been.

The following code shows how to automatically invoke the sdk to read a barcode and fill an input box.
