Connection between pysical product and ecommerce product

Hello,

>will i enter the barcode text from the physical product in the sku field in the product in ecommerce ?

This is one of ways to do it. But if SKU field already in use, you might want to use some other field for thispurpose. There a few options:

1. This plugin creates new empty field called “Barcode” for all products (for variations too), so you can use it for barcode text.
2. You can create custom field using plugins like “Advanced Custom Fields” and specify its meta name in the “search fields” setting, so scanner will be using this field for search too.
3. There are plenty of other plugins which creates EAN, UPC, Barcode fields for each product. So, you can use any of them for string barcode text. List of integrated plugins you can find here: https://www.ukrsolution.com/Wordpress/WooCommerce-Barcode-QRCode-Scanner-Reader
