This icon is a bunch of squares and lines that are really random. They represent a code that can be scanned by devices to tell you what product they represent. Each one is unique to each product.
This QR Code icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,500 icons, all in the same style and quality.
