Yes. Alongside QR codes, you can generate traditional linear (1D) barcodes in several common formats: Code 128, Code 39, EAN-13, EAN-8, UPC-A, UPC-E, and ITF-14, the same kinds of codes used on retail products and shipping labels.
You can customize the size and the foreground/background colors, and choose whether to show the human-readable text (the numbers) underneath the bars. Like static QR codes, a barcode encodes fixed data directly, it's not trackable or editable after creation, and it can be downloaded as an image once generated.
