Scan and create barcodes. Point the camera at a label to read it. All codes in the frame are scanned at once. Each code has a matching number on screen and on its card below. The camera keeps running while results are displayed. Select a barcode type and enter the digits to create a code. Input is checked against the format's specification as you type. An incorrect number of digits or an invalid check digit prevents saving, and the reason is displayed. Save the barcode as a 1024px PNG or share it directly.
