For EAN-8, EAN-13, UPC-A, and UPC-E type barcodes, the entry method provided is a fixed-count decimal digit input box. To enter a number, click on the first digit to select it, then begin typing the number. As you type, the check digit (marked) will change to reflect the current digits. You do not need to type the check digit. Digits can also be pasted from the clipboard, by selecting any digit then pressing Ctrl+V.

The number can also be entered directly using a barcode scanner. When a barcode scanner is attached to the computer in the "Keyboard Wedge" mode, scanning a barcode will simulate the typing of the number via the keyboard. So under these circumstances, you may select the first digit in the entry box and then scan a barcode; the digits will be entered into the box.
