How Do Barcodes Work?

Barcodes use a scanner that sends out a laser to detect parallel lines and numbers. When this laser reaches a particular frequency, that sweeps across the barcode and absorbs light, and reflects the rest.

There are two types of barcodes: linear (also known as traditional, or 1D) and 2D barcodes, which require two different readers to scan each one. Linear codes can be read with what is known as a ‘traditional laser scanner’, whereas 2D barcodes require a camera-based imaging scanner.

Advantages of Linear Barcodes – The main advantage of linear barcodes over 2D barcodes is that they save time while increasing inventory accuracy.

Advantages of 2D Barcodes

2D barcodes, unlike linear ones, use squares, hexagons, dots, and shapes that can be encoded both vertically and horizontally. The benefits of this are, you can hold a much larger portion of data in a smaller space. They are also inexpensive to create and can be read by your consumers with ease, especially if utilised for marketing purposes such as through social media promotions.

How Can You Read Barcodes?

The first 6 numbers of a linear barcode are the manufacturer’s identification number.
The next 5 digits represent the item number and the last number is called a ‘check digit’ which enables the scanner to determine if the barcode was scanned correctly..
