Generate a unique barcode for each order. WooCommerce Order Barcodes generates unique barcodes for every order placed on your site. These barcodes can be used on e-tickets, e-reservations, packing slips or anything else that would benefit from having a scannable barcode attached to it. Barcodes can be created as one of five different types (from standard barcodes to QR codes) and can be scanned and processed directly on your site. Customers will receive their barcodes by email so they can be easily printed out where necessary.
