2D Barcode - What is the difference between 1D and 2D barcodes?

The primary difference between 1D and 2D barcodes lies in their scanning requirements and the type of data they can store. While 1D barcodes can be read with a laser barcode scanner, 2D barcodes necessitate a 2D imager. Additionally, the choice between these two types of barcodes may depend on specific supply chain requirements or industry-specific applications that favor a particular barcode type.
