To manage barcode in the product, open the plugin settings (YITH Plugins -> Barcodes and QR Codes) and activate the option Enable for products.
Choose the barcode protocol you want to use on your website: explore the Product barcode protocol and you will see a dropdown menu that you can use to select one among many different barcode types, such as EAN-13, STD-25 and QR CODE.
Create barcode automatically
You can let the plugin generate the barcodes both for the products already available and the new ones that you will create.
If you want to generate a barcode for all the products of your shop in an automatic way, click on the specific button that you find in the “Tools” section of the plugin settings dashboard. You can also choose whether to include variations or not.
If you want to assign a barcode automatically to a newly created product, enable the entry New products in the plugin settings dashboard and disable the Enable manual barcode entry.
Create barcode manually
If you want to assign the barcodes to the products of your shop manually, enable the Enable manual barcode entry in the plugin settings dashboard and disable the entry New products.
This feature is particularly useful in case you have products that already have a barcode or in case you wish to handle the codes manually.
Now you will be able to see the barcode and you will have the chance to add one manually by editing the product page.
The plugin allows managing barcodes also for variable products: whether automatic or manual management, you can set a barcode for every single variation.
Show barcode in the product page
The product barcode is shown on the product detail page only if the Show in product page option is enabled.
